Corundum thermal insulation: technical characteristics of insulation. Liquid thermal insulation Corundum: characteristics, advantages and disadvantages Heat-insulating paint corundum

Ultra-thin thermal insulation Corundum is a paint composition used to reduce heat loss from buildings, pipes, tanks and other objects. I will briefly describe the principle of operation of the paint, talk about its varieties and give tips on how to use it yourself.

What you need to know about thermal insulation paint

How does liquid insulation work?

Liquid ceramic thermal insulation, which includes Corundum insulation, has a complex structure. Usually, the paint consists of four components:

The basis- acrylic or latex dispersion with water as a solvent. Connects all components into a single complex, is responsible for securing the insulation to the object and for the formation of a continuous film.

Granules- carriers of basic thermal insulation properties. These are perfectly round spheres made of ceramics or foam glass. Inside the granules there is either a vacuum or very rarefied air, which ensures a decrease in thermal conductivity.
Pigment. Liquid insulation still belongs to the category of paints, which is why colored components are added to it. Usually the compositions are made white, but sometimes they are also tinted - products for ordinary acrylic are suitable.

Modifiers. Various additives that improve the functional characteristics of paint. This may include silicone, which prevents cracking of the material, anti-corrosion components, additives that increase cold resistance, etc.

When applying paint to the surface, the granules are distributed in the base and cover the object to be insulated. The cavities inside the granules act as an insulator, and the thermal conductivity of the coating is significantly reduced. This is facilitated not only by the large number of hollow inclusions, but also by their tightness.

Pros and cons

Corundum insulation (along with similar compounds) is rapidly gaining popularity today. This is facilitated by a number of quite objective advantages of this paint.

On the other hand, Corundum also has disadvantages, and for the sake of objectivity in the table I will present the main pros and cons:

pros	Minuses
Little labor intensity. The composition is applied to a surface of any shape no more difficult than ordinary paint. In this case, there is no need for either the construction of a frame or subsequent cladding. The possibility of mechanical application further reduces the labor intensity of the work.	Moderate thermal insulation. When treated with Corundum, the reduction in thermal conductivity will not be bad - but by no means outstanding. If we take into account that the material is extremely rarely applied in a layer of more than 2 mm, then the heat loss will still be noticeable.
Small increase in size. The paint demonstrates sufficient efficiency even with a layer thickness of 1 mm. Thanks to this it is possible to provide high-quality insulation even nearby objects.	Efficiency at different temperatures. The higher this indicator, the better the paint works. That is why such products are used mainly for hot pipelines and tanks. On cold water pipes, facades and other structures, I would rather consider such material as additional insulation.
Durability of the coating. The material adheres well to most surfaces (concrete, brick, metal). At the same time, correctly applied paint does not deform or crack when the substrate temperature changes.	High price. The situation is further aggravated by the fact that Corundum needs to be applied in several layers, so the material consumption will be considerable.

Varieties of Corundum

The range of heat-insulating paint compositions is quite extensive. That is why the choice of Corundum material should be made only after studying the entire available line.

The most popular varieties:

Corundum Classic. Basic option liquid insulation, which is used to finish almost any surface - from facades to cold water pipes. Optimal thickness application - up to 0.5 mm.
Corundum Anticorrosive. It can be applied to the surface without anti-corrosion treatment - it is enough to perform initial cleaning of loose rust flakes. Combines the functions of a heat insulator and a corrosion inhibitor.

The price of the material is higher than that of standard insulating paint. In order to save money, the first layer can be done using “Anticor”, and then use the more affordable “Classic”.

Corundum Facade. Focused primarily on painting concrete surfaces. The material can be applied in a layer 1 mm thick, and after drying it retains high vapor permeability. Also, dried paint is suitable for finishing with facade compositions (paint, decorative plaster).

Corundum Winter. One of the few warm insulating materials, suitable for use in winter. Work can be performed at temperatures down to -10 °C, without affecting the adhesion and strength of the applied material.

Application technology

Method 1. Mechanized processing of facades

Thermal insulation Corundum can be used for finishing walls from the most different materials. To do this, it is convenient to use sprayers - and brief instructions will help you choose the optimal sequence of actions:

Illustration	Work stage
	Mixing the composition. After opening the container, mix the paint to distribute the granules in the binder. To avoid destruction of ceramic inclusions, mix either manually or with a mixer at low speed.
	Preparing the spray gun. Before starting work, remove all filters (usually in the receiver and gun handle) - they will trap granules and quickly become clogged. After this, fill the reservoir with mixed paint.
	Surface preparation. We clean and remove dust from the façade, removing loose fragments. When applying Anticorrosive paint to a metal surface, we remove rust flakes: brushing or complete cleaning with a sandblaster is not necessary.
	Coloring. Spray the composition over the surface in a layer of no more than 0.3–0.5 mm. The next layer can be applied only after the previous one has dried.

Method 2. Painting thermal insulation of pipes

Corundum paint can also be applied with your own hands using a roller or brush. I will tell you about this processing method using the example of thermal insulation of pipes:

Illustration	Work stage
	Mixing paint. As in the previous case, thoroughly mix the composition immediately before application.
	Pipe preparation. Using a metal mesh, brush or emery, we clean the pipe from rust.
	First coat of paint. Apply Corundum thermal insulation with a brush or roller. Thoroughly rub the paint to form a layer no thicker than 0.5 mm.
	Repainting. We wait for the composition to dry and repeat the operations until the designed thickness of the thermal insulation layer is reached.

Conclusion

Despite some disadvantages, Corundum thermal insulation is quite effective - but it is important to apply it correctly. In the selection of materials and in the study of processing techniques different surfaces The video in this article will help you. In addition, you can ask any questions you have in the comments below.

Thermal insulation paint CORUND FACADE created specifically for the construction industry and is used for ultra-thin thermal insulation of plastered, concrete, brick, wood and other surfaces of building envelopes and structures.

Avoid freezing!

Preparing the surface for application

Prepare the surface for application of the material: remove loose areas, open cracks, remove oily inclusions, clean the concrete from cement laitance, repair the surface, including inter-brick joints to reduce material consumption and excavations deeper than 5-7 mm, with cement-plaster compounds. Clean the surface using sandblaster, metal brush or abrasive wheels for removing gloss on surfaces and removing falling off and crumbling structural elements.

After machining The surface should be thoroughly dusted using brushes or blowers. After dust removal, the surface must be washed with water to remove dirt, remaining dust, etc. Wait until it dries completely. Concrete, brick and similar surfaces must first be primed with YAKHONT deep penetration primer. If it is necessary to apply CORUND FACADE coating to metal surfaces– the metal must first be protected from corrosion.

It is recommended to first apply 1-2 layers (0.5 mm each), depending on the condition of the metal surface, modification CORUND Anticor. Concrete humidity when applying CORUND FACADE should not exceed 4%, air humidity during application should not exceed 80%. In the presence of oily and greasy stains on the surface - they must be removed with a solvent.

Preparation of insulating coating CORUND FACADE

CORUND FACADE is ready for use; it must be mixed, if necessary, adding a little distilled water, immediately before application to a previously prepared surface. The amount of water also depends on the temperature of the application base and subsequent use. When applied to a surface with a temperature from +7°C to +80°C, the amount of water added to the material can be no more than 5% when applied with a brush and no more than 3% when applied mechanically (airless spraying apparatus). When applied to surfaces with temperatures above +80 °C, it is necessary to first reduce the temperature by applying several primer layers of CORUND FACADE material, diluted with 40-50% distilled water according to the scheme (see coating application). At long term When stored inside the container, separation into fractions is allowed.

Do not over mix! When using a drill with a paddle attachment or a mixer, the maximum permissible mixing speed is 100 rpm. Exceeding the rotation speed will lead to the destruction of the microsphere and a radical reduction (or cancellation) of the effectiveness of the thermal insulation coating. Using vertical movements of the blade to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the curds with the liquid.

Stir until the product resembles cream. Approximate mixing time:

Mixer 3-8 minutes,
Manual stirring for 7-10 minutes.

If the task is to eliminate condensation, a “coat” of frost, fungus, mold, the material is applied with a minimum addition of water, with a maximum interlayer interval (over 24 hours).

Coating

It is recommended to work with Corundum Facade using a soft brush with long natural bristles or an airless spray. You can apply the coating to small surfaces or areas with complex configurations using a soft brush. Surfaces from 100 m2 can be treated using an airless sprayer with a material pressure at the nozzle exit of 60-80 bar

Important: not all airless sprayers are suitable for working with Corundum Facade paint!

The insulating coating can be applied to surfaces with temperatures from +7ºС to +120ºС. You cannot work in wet weather, because... The material is liquefied by water and will not dry out. The period for complete drying of one layer of coating with a thickness of 1 mm is at least 24 hours. The next layer can be applied only after the previous layer has completely dried - after 24 hours at a temperature not lower than +7°C during the entire drying period. A layer of about 1 mm is obtained with approximately three to five “passes” of the sprayer or brush. Applying the material in a thicker layer is unacceptable, since this leads to the formation of a moisture-proof film on its surface, which in turn prevents the complete evaporation of the moisture contained in it, which will lead to the annulment of the thermophysical properties and deformation of the coating.

When applying the material to a surface with a temperature above +80ºС, the material boils and “sets” very quickly, so the material must be diluted with water. It is recommended to prime the surface with a 40-50% aqueous solution of the material. When applying CORUND FACADE on surfaces with temperatures above +80 °C, the thickness of the maximum layer within 24 hours should not exceed 0.5 mm! The hotter the application surface, the more the material is diluted. The diluted material is applied with quick short movements; with this application the layer will be very thin. The drying time for each layer is at least 1 hour. Such layers are applied until the applied material stops boiling on the surface. After this, allow to dry for 24 hours. Then the material is applied according to the usual scheme - with the addition of 3% to 5% distilled water in layers up to 1 mm with interlayer drying for 24 hours. The thickness of a layer of 1 mm can be determined with a thickness gauge of the “painting comb” type, with a material consumption of 1.1 liters per 1 m2 (approximate consumption when applying the coating with a brush to flat surface) or the thickness of the “optical density” of the material (so that the underlying material does not show through). The material consumption is affected by the type of surface and method of application. The total thickness of the coating and the number of layers are determined by thermal engineering calculations.

Safety precautions when working with CORUND FACADE

At normal conditions the product is safe. If the room is well ventilated or work is carried out outdoors, respirators are not required. In rooms without ventilation, use standard respirators. Use safety glasses to protect your eyes. Use gloves and protective clothing to protect your skin.

If the product gets into your eyes, immediately rinse your eyes with running water for 15 minutes. If irritation persists, consult a doctor. In case of contact with skin, wash with soap and water.

The product in liquid state is not flammable. In the event of a fire in structures or structures on which the coating has been applied, use water, foam, dry chemicals And carbon dioxide. In case of product spillage, use any absorbent material such as sand, soil, etc.

Storage and transportation conditions

The CORUND FACADE material is stored in tightly closed containers at temperatures from +5 °C to +30 °C, air humidity no more than 80%, away from direct sun rays. Transportation is carried out by any type of transport at temperatures above +5 °C away from direct sunlight. Packaging of cargo for transportation must ensure the correct installation of containers and the safety of the container. Violation of the integrity of the container leads to damage to the material.

Liquid ultra-thin insulation (as an analogue) is a new word in the matter of insulating structures. Standard methods of thermal insulation are still good, but little by little they are being replaced by more effective solutions.

Liquid insulation is just such a solution. It is able to protect the structure from freezing, while being essentially more paint and varnish material, than insulation in the form in which we usually imagine it.

In this article we will present for your consideration all the nuances and features of liquid thermal insulation Corundum.

1 Features of liquid insulation

Liquid thermal insulation Corundum is produced by the Fulleren company association. They have been producing this material for many years and have managed to achieve quite serious results.

Note that liquid-type thermal insulation was not invented quite recently. It is intended for the same insulation work, but it is reproduced in a unique form.

Standard insulation is a special material with low thermal conductivity. It cannot transfer heat and perfectly delineates zones with different temperatures due to the presence of a large amount of air in it.

That is, the insulation has a certain thickness and is laid on the surface of the walls, thereby protecting them from the effects of external temperatures. As you yourself know, the working thickness of the slab can reach up to 10 cm or even exceed this figure.

But the characteristics of the heat-insulating material Corundum are completely different. It’s not for nothing that this insulation is called liquid. If you look at it uninformed, the composition can be confused with ordinary paint.

Indeed, thermal insulation of this type resembles paint in consistency, is applied like paint, and even forms a similar coating. However, after application, an ultra-thin thermal insulation film with unique parameters is formed.

This is possible thanks to the unique structure of the Corundum material (as with).

1.1 Insulation composition

In addition to the standard name in the form of liquid thermal insulation, this insulation has another name - ceramic.

It is not called ceramic because it consists of ceramics or forms a ceramic surface. Quite the contrary, the main filler in Corundum insulation is an acrylic-type polymer, only more dense.

Ceramic insulation consists of ceramic hemispheres with insulated filling. These hemispheres allow you to create insulation with a thickness of 1-2 mm.

However, ultrathin film does not consist of hemispheres alone. It also contains anti-corrosion additives, polymers, etc.

Together they form insulation for walls, floors, ceilings, pipes and generally any structures available to you.

After hardening, the polymer sets, forming a very strong film; inside it there are frozen spheres that occupy more than half of the space. They repel any thermal energy, protecting the insulated structure no worse than a quite impressive-sized layer of mineral wool.

1.2 Operating principle

The instructions for use state that Corundum insulation with a thickness of only 1 mm can replace up to 5 cm of mineral wool insulation. This is truly ultra-thin thermal insulation. But how does she manage to do this?

And everything is very simple. The fact is that when creating Corundum insulation, the developers were initially guided by the desire to eliminate heat loss in all three main directions. And you probably know these directions.

Heat loss building structures most often occur due to:

Heat transfer;
Convection;
Radiation (even if it costs).

Heat transfer is dampened by most standard insulation materials. But at what cost? To level out the temperature difference, a person has to use bulky insulation with a thickness of 5 cm.

In this case, it must be laid on glue or in a special frame, and then covered again. Liquid thermal insulation performs the same functions, only its structure is tens of times denser, and its thermal conductivity is almost zero.

That is, when finishing the walls, the applied liquid will also prevent the air from exchanging temperature with their insides, but at the same time, an ultra-thin film acts as protection.

Convection is the transfer of heat from object to object. An extremely controversial method, because in ordinary construction it plays practically no role.

However, even this moment is liquid ceramic thermal insulation material Corundum can completely remove.

But with radiation things are much better. Standard insulation materials are not capable of extinguishing thermal radiation (for example, they are ineffective).

That is, they can only transfer the radiation onto themselves, but a certain amount of it will still reach the surface of the walls. Meanwhile, radiation comes from all warm objects, especially from heaters.

For additional protection I had to combine regular insulation with foil. The foil reflected the waves, and the insulation did its usual tasks.

But liquid thermal insulation Corundum repels radiation by almost 90%. The residues are simply extinguished and dispersed close to the surface of the walls.

The result is a situation where all three main consumable items are removed by just one ultra-thin protective film. Surprisingly, customer reviews are also completely unanimous. Corundum insulation really works and does its job well.

1.3 Pros and cons

When selecting thermal insulation, it is important to pay attention to all parameters. Take into account specifications, reviews and even consumption. However, first of all you need to look at the properties of the insulation. Why is it good, and why, on the contrary, does it repulse you?

The developers eat their bread for a reason. Corundum insulation has a huge list of advantages and a minimum of disadvantages. So let's look at them in more detail.

Main advantages:

Can be applied to walls, floors, load-bearing structures, roofing, pipes, etc.
The work is done with your own hands; improvised means will do.
Dries quickly.
A thin protective layer replaces up to 5 cm of standard insulation.
Not exposed to external influences.
Not afraid of moisture.
Does not respond to temperature changes.
Non-flammable.
An elementary method of application as in the case with.

And this is not the whole list. Full characteristics can be assessed only after you have the instructions and certificates for Corundum thermal insulation in your hands. But even from this it follows that the material is extremely useful.

Just look at the fact that it can be applied with a regular brush. That is, any structure that can be reached can be processed.

Now remember standard processes insulation. How much time does it take to decorate one column with mineral wool? And what can we say about the surface of the walls, which are surrounded by a large number of pipes?

While Corundum insulation will not cause you such problems. All you need to do is stir it and apply it to the wall. It is not surprising that the reviews about it are all positive.

Main disadvantages:

Quite a high price.
Serious expense.

As for the shortcomings, they are quite trivial. Like any innovative material, Corundum insulation is expensive. These are already production costs.

The second point, which partially overlaps with the first, is the serious waste of paint. Corundum must be applied in several layers. Accordingly, the consumption of such material will be very serious.

It is advisable to apply at least 4-5 layers to the surface of external walls. This is the only way to create insulation High Quality, and be sure that it will not crack or peel off.

2 Types and differences

Corundum insulation comes in several varieties. Each of them has its own technical nuances.

There is Corundum insulation:

Classic;
Facade, Facade-Lotus;
Anticorrosive;
Winter;
Fire protection.

Liquid thermal insulation Corundum Classic – standard option, which is used almost everywhere. Thermal paint is easy to apply, dries quickly and has good strength parameters.

Thermal insulation Corundum Facade is intended for exterior finishing walls The Facade-Lotos sample is the front, second level of insulation. Apply for added protection.

Anticorrosion model – insulation with enhanced anti-corrosion properties, ideal for protecting wood.

The Winter model differs only in the possibility of application at sub-zero temperatures.

Well, the last option is paint, which swells upon contact with fire, protecting the structure from fire.

Heat retention indoors largely depends on the thermal insulation parameters of the building itself and the finishing materials used. Reliably insulating a house means reducing heating costs. Today, the construction industry offers many types of insulating materials, which vary in their characteristics and costs. One of the most optimal options is liquid thermal insulation Corundum, which is characterized by durability and excellent thermal insulation properties. Let us consider in more detail the features of the composition, selection criteria and application technique.

The unique composition of thermal insulation is also called heat-reflecting paint, since with a layer thickness of only 1 mm it can have a noticeable energy saving effect. Thanks to this, Corundum thermal insulation is very economical in consumption. The filler consists of microscopic hollow spheres - ceramic, polymer, composite, glass balls, which are filled with rarefied air. Such microparticles can vary not only in composition, but also in the size of microgranules, percentage, homogeneity of components, etc.

Externally ceramic superfine paint practically no different from regular paint on acrylic base. Despite the fact that today the construction market offers several varieties of ultra-thin insulating compositions, almost all of them have a similar structure:

The thermal paint is based on a water-acrylic solution. Its properties make it possible to ensure uniform distribution of thermal insulation components over the working surface. In addition, the composition promotes better fixation of liquid ceramics.
The binder also contains various kinds additives that improve the performance parameters of thermal paint. The most common material additives include natural and artificial rubbers, silicone, etc.

Liquid thermal insulation Corundum: technical characteristics and principle of operation

The temperature range for thermal paint varies from -65°C to +260°C. The main technical characteristics are vapor permeability and hygroscopicity of liquid insulation, which can be applied to almost any type facade material: concrete, stone, brick, metal, plastic, etc.

This material guarantees the removal of condensation that forms on walls and pipes in the room. The composition of this warm paint includes special fixatives, catalytic substances, anti-corrosion additives, as well as a binder base based on high-strength acrylic. Along with the content of microspheres, this composition is easily applied and distributed over the entire surface, providing good energy saving and thermal insulation.

An important argument for buying liquid thermal insulation Corundum is the safety of the substance. Thanks to the content of natural additives and environmentally friendly components, the treated surface is non-toxic and does not emit any odors. This allows you to use thermal paint to insulate any room. You can create a stable thermal barrier even in children's rooms or homes where there are allergy sufferers.

The thermal insulation properties of the composition can be achieved in several ways:

Through convection, i.e. heat transfer by the thermal paint layer itself. Due to the fact that most specific gravity Liquid insulation consists of hollow balls; losses due to convection in the composition are completely insignificant.
Thermal conductivity of a material, when heat is transferred from a hotter part of the surface to a colder place. In liquid insulation, only 20% of the binder component has thermal conductivity properties.
Radiation is a phenomenon in which heat transfer occurs through internal energy suspensions. In energy-saving paint, microscopic spheres are endowed with the properties of heat reflection and dissipation. Almost 90% of the reflected radiation converts work surface walls into an analogue of a thermos.

Advantages of thermal insulation Corundum

Liquid heat-saving paint is an innovative composition that differs from all existing coatings. Among the most significant advantages of its use, the following aspects should be highlighted:

The versatility of the substance. It can be applied to any type of surface, including untreated, if this is indicated on the instructions for use. Specialists use thermal paint to treat brick, concrete, metal, plastic surfaces, as well as thermal insulation of equipment and air ducts.
Wear resistance. The applied layer of liquid insulation does not degrade over time. Corundum provides a guaranteed service life of up to 15 years, and with proper care (timely cleaning, high-quality finishing), this figure can be doubled.
Ceramic thermal insulation has good adhesion to any type of material, which ensures good protection from the entry of moisture and air.
The substance is resistant to alkaline environments.
Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
Ceramic thermal insulation is practical and easy to apply to surfaces of complex geometric shapes.
The material is ultra-light, so there is no additional load on the structure. Due to this property, thermal paint is often used when treating roofs.
The substance is quite convenient to repair, because... In case of minor damage, the old layer can be easily removed and replaced with a new one.
Thermal paint reflects up to 80% of the energy of ultraviolet rays.
In addition, liquid insulation is fire resistant. When heated to +260°C, the applied layer is charred, and when it reaches +600°C, the thermal paint begins to decompose, releasing carbon and nitrogen oxide, which prevents the rapid spread of flame.

Disadvantages of ultra-thin thermal paint Corundum

Despite the impressive list of advantages of the material, it is not without some disadvantages. Among them, the following aspects should be highlighted:

High cost of thermal paint.
Since ceramic thermal insulation is relatively New Product in the construction market, there is still no time-tested evidence that the material meets the declared characteristics.

Main types of thermal insulation

Liquid ultra-thin thermal insulation is available for sale in specialized construction stores in several versions. The entire line of polymer compositions consists of the following types:

Thermal insulation Corundum Classic is a liquid suspension intended for roofing and facade work. This composition has also found application in interior decoration premises, providing reliable thermal insulation of walls in residential buildings and buildings general purpose. Besides, classic variety highly effective for insulating concrete floors, self-leveling coatings, hot and cold water supply communications, as well as insulation of window slopes.
Corundum Anticor is a special anti-corrosion composition that can be applied simply to a rust-covered surface, without special treatment. This thermal paint has high adhesion to concrete and metal, creating a reliable protective and insulating layer. As a rule, this liquid thermal insulation Corundum is slightly cheaper in price than the classic type and is used to create the first base layer of insulation.
Facade is a type of heat-saving paint intended for treating concrete surfaces, as well as buildings made of slag or foam blocks. The composition is applied in a thicker layer, thereby reducing the labor cost for treating large surfaces. This type Warm paints are usually used for finishing.
Winter – liquid thermal insulation intended for work in the cold season. The principle of energy saving is based on the “thermal mirror effect”, i.e. reflections of flows of heated air masses. This composition is universal and can be applied to almost any surface at ambient temperatures down to -10°C.

General criteria and features of selection

Ceramic thermal insulation is not yet a fairly common type of coating, which is due to the high cost of the product. However, experts claim that this substance has exceptional performance characteristics, the value of which significantly exceeds the cost of acquisition. To choose optimal view liquid thermal insulation, it is important to take into account the following features:

The first thing that affects the final result of ceramic insulation treatment is the density of the composition. High-quality thermal paint is characterized by an indicator of about 0.6 kg per 1 liter of product. Those. The weight of a standard 10 liter bucket should not exceed 7.5 kg.
It is also worth looking at the container with the solution “through the light” to determine the degree of its separation. Good indicator quality and efficiency of thermal insulation properties will be dense upper layer substances. As a rule, ceramic spheres have a light fraction that rises to the top. Thus, the thicker the top layer, the higher the thermal insulation properties.
No less important criterion The choice is the structure of the suspension itself. To determine it, you need to rub a couple of drops of heat paint between your fingers. IN quality composition microgranules of ceramic balls are felt, i.e. the substance has roughness.
In addition, it is necessary to take into account the color of the liquid thermal insulation. Corundum is produced in white color, so gray or yellow paint is a clear indication of a counterfeit product.

Application area

Ultra-thin ceramic insulation Corundum is an innovative material that forms a durable elastic coating that reliably protects the surface from moisture, overheating and corrosion. This composition is used in the temperature range from -65°C to +260°C.

The main areas of application of thermal paint include:

housing and communal services facilities (including treatment of pipelines for various purposes, thermal insulation of facades, roofs, windows, walls);
transport industry;
oil industry;
insulation of thermal power structures;
construction industry.

Ceramic insulation technology

It is necessary to apply ultra-thin thermal insulation Corundum to a previously prepared surface, regardless of the modification of the composition. The basic rules that should be followed before starting paint insulation include the following:

If ceramic insulation is intended for wall treatment, the working surface should be cleaned of dust and dirt, and existing gaps and chips should be expanded and filled with cement mortar.
Before painting thermal insulation on concrete slabs, they should be cleaned of “cement laitance”.
It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a stiff metal brush.
If you plan to treat a metal surface, it must be dust-free and degreased (substances recommended by the manufacturer are Solv-Ur, Solvent). To paint objects made of non-ferrous metal, it is necessary to remove the gloss and apply primer VL-02 or VL-023.
It is also worth considering that it is necessary to dilute ceramic thermal paint immediately before applying it to the wall.

Important! It is recommended to mix liquid thermal paint Corundum manually. However, for work with large volumes, it is permissible to use a construction mixer, the rotation speed of which should not exceed 200 rpm. Otherwise, there is a risk of destruction of the hollow ceramic granules, which will negatively affect the thermal insulation properties of the composition. As a rule, manual mixing takes 10-15 minutes. When working with a construction mixer, this figure will be 3-7 minutes.

It is also worth considering that in some modifications of the composition it is necessary to add water before starting work, so you need to carefully study the manufacturer’s instructions. The volume of liquid depends on the purpose of thermal insulation; in any case, the required proportions are indicated on the packaging of the composition.

The technique of applying ultra-thin thermal insulation Corundum is carried out in three ways:

using air spray devices;
airless spray method;
manually - using a roller or brush.

The manufacturer recommends applying the composition in three layers, and the consumption should be 1 m/m2. When working on thermal insulation, this composition does not require additional ventilation in the room, nor the use of special personal protective equipment.

To guarantee the effectiveness of the result, it is important to strictly follow the manufacturer’s instructions and fully adhere to the recommendations indicated on the packaging.

Conclusion

The use of ceramic thermal paint is an innovative approach that has undeniable advantages over traditional methods thermal insulation of surfaces. The article discusses the main features of liquid thermal insulation Corundum, reviews, selection criteria and methods of applying the composition. The resulting coating layer is lightweight, has excellent performance characteristics and ease of use.

Features of choosing liquid insulation Corundum. Video:

Thermal insulation Corundum is a substance in liquid form that is produced on a water basis. The main component of such products is a latex-polymer mixture. The scope of application of this material is very wide: from insulation residential buildings inside and outside to protect industrial equipment and various pipes.

Liquid thermal insulation Corundum is a mixture based on an acrylic binder and ceramic microspheres, which have thin walls and contain rarefied air inside. Acrylic binders are created using substances from the group of catalysts and fixatives.

Microspheres have sizes up to 0.5 mm. In addition, it contains various additives, so if Corundum is chosen, the facade will be processed very efficiently, since such additives enhance certain qualities of the product. The composition is completely balanced, so the material is elastic, light and stretchable. In addition, the Corundum coating has good adhesion.

The consistency of the substance resembles plain paint. This is a whitish suspension. The material not only has thermal insulation properties, but is also able to protect metal parts from corrosion.

In addition, Corundum is a thermal insulation that has many other advantages:

Keeps warm well. It has been established that 1 mm of such paint is comparable in its ability to conserve heat with 5 cm of roll-type insulation (for example, mineral wool). The reviews are very good.
It is easy to apply the substance to surfaces. The paint must be applied using conventional tools. You can use a spray gun, roller, or brush. The product does not emit harmful compounds, so respiratory protection is not required.
If Corundum is chosen, the facade will be protected from various damages due to the influence of aggressive environmental factors. For example, metal will not rust. Wood does not dry out or rot. The brick, concrete layer and plaster do not crumble and cracks do not appear on them.
If Corundum is applied, the facade will not be destroyed due to the influence of rodents, insects, bacteria and other pests. The surface does not rot. Mold does not form either.
The insulation layer is lightweight. If Corundum is chosen, the facade will not have additional load, as if other insulation materials were used, for which it is necessary to install additional special retaining structures. Due to the light weight of the layer, Corundum can be applied even to fragile surfaces.
There are no seams. Thanks to this, there will be no cold spots. The thermal insulation layer will be seamless, so the cold will definitely not be able to penetrate into the room.
Durability. It is enough to apply the product only once, and you will not need to replace such a layer for a long time.
The use of the material is also associated with its environmental friendliness. During long period During operation, such a layer does not emit harmful components. The product can even be used in homes where people who are prone to allergies live.
Neither the area of the room nor its geometry is affected, which is taken into account when using bulky structures. Corundum will not affect the dimensions and shape of the building.
Can be used as a finishing material. Special components from the group of pigments are added to this paint, so it is also used as a decorative coating.

But it must be taken into account that such a heat-insulating layer also has its drawbacks. First of all, this concerns the high cost. The material appeared on the construction products market not so long ago, so the price is still quite high. However, this drawback is offset by the fact that thermal paint retains heat well and the layer will last quite a long time. You also need to take into account that the material, as reviews indicate, hardens very quickly, so you will have to apply it quickly.

Types of paint Corundum

Ultra-thin thermal insulation Corundum comes in several types. These modifications differ from each other in properties and some features:

Corundum Classic. This substance is different high efficiency and is great if you need to insulate walls inside and outside, facades, roofs, concrete screeds, pipes (both warm and cold), window slopes, etc. Corundum Classic is also suitable if you need to properly process existing air conditioning systems and steam lines. In addition, Corundum Classic prevents condensation from forming on the surface, and such a layer reduces heat loss.
Anticorrosive This insulation is unique due to the fact that when applied to metal surfaces it prevents corrosion. The uniqueness of this product also lies in the fact that it can be applied to an already rusty layer. It only needs to be removed by rubbing thoroughly. This substance prevents further corrosion processes. In addition, the material also has good thermal insulation properties.
Corundum Winter. It is allowed to work with such a product in slight frost, that is, even if the air temperature is minus 10°C. It will not freeze or undergo polymerization due to low temperatures. For conventional ceramic type heat insulators limit temperature is only +5°C. Corundum Winter contains acrylic-type polymers and foam glass microgranules that are dispersed in them. Thermal paint Corundum additionally includes pigments, rheological components, inhibitors and a fire retardant, which is important to consider when choosing.
Corundum Facade. This is another paint modification. It was developed specifically to be applied to concrete surfaces. The use of such material is associated with heat-reflecting properties. It is necessary to apply paint in a large layer to speed up the process. In addition, this product is resistant to environmental factors and has good vapor permeability. Excellent for facades and as a decorative layer.

Another option is edel facade panels. They are perfect for those people who want to take advantage of finishing material from the famous manufacturer Edel. There are several varieties of such panels (about 3-4 can easily be combined with each other). Edel corundum is one of the types of such facade panels, which are made with a texture like finishing stone. Reviews of this material are positive.

Specifications

Corundum paint has technical characteristics that allow it to be used for structures with different purposes and configurations. Even if the layer is minimal, the product still remains a good insulator.

The following main characteristics of Corundum paint are distinguished:

Thermal conductivity. The indicator is approximately 0.0012 W/(m*S). This parameter is noticeably lower than that of other materials that are used as heat insulators (for example, this applies to mineral wool, polystyrene foam, etc.).
Moisture resistance. The substance will not allow water to pass through. In addition, the layer is not destroyed by moisture. Even solutions with a high salt content will not have an effect.
Vapor permeability. The paint does not form an airtight film, so it will not interfere with air exchange in the room. Thanks to this, an optimal microclimate is maintained inside.
Fire resistance. The material is not subject to combustion. When the temperature rises to 800°C, the paint simply begins the process of decomposition. As a result, nitrogen and carbon oxides are released. If the temperature is 260°C, then the heat-insulating layer simply becomes charred. By fire safety such material belongs to categories G1 and B1, that is, it does not burn or ignite.
Adhesive properties. The indicator may differ depending on the surface itself on which Corundum insulation is to be applied. For example, if a concrete layer is used, then the index is 1.28 MPa. For steel it is 1.2, and for brick - 2.
Operating temperatures include a range from -60°C to 260°C.
Impact resistance ultraviolet radiation. The material will not deteriorate when exposed to direct sunlight. It can be used even without a special protective layer.
Biological resistance, that is, the material is resistant to the action of fungi, mold, and bacteria. It won't rot. In addition, rodents and insects will not be able to eat such coating.
Environmental friendliness. This ceramic type paint does not emit toxic substances, even if it is heated. In addition, when applying it, you do not need to use special means personal protection.
Operating time. This coating is durable. It can last at least 10 years. During this time it will not collapse or become covered with cracks.

Application instructions

Before you start applying Corundum paint, you need to choose the right material. You should not buy products from unverified sellers. The manufacturer is Russian company Fullerene. In addition, there is a network of distributors. Be sure to pay attention to the condition of the paint. It should have the form of a suspension of paste-like consistency with a whitish tint. Traditional packaging is a plastic bucket. It can be of different volumes. The label must contain information about the manufacturer.

As for the cost of Corund paint, it differs depending on the type of material and the place where sales are made. For example, in Russia the cost of the Classic modification for 100 ml is approximately 34 rubles. Anticor coating can be purchased for 450 rubles per 1 liter. Corundum costs from 400 rubles per 1 liter, and Corundum Winter - from 550 rubles.

To apply thermal paint, you need to stock up on the appropriate painting tools. This can be a spray gun, roller or brush. It is best to apply paint using the first option, since it not only reduces the consumption of the substance, but also makes the coating better.

The thickness of one layer of paint should be approximately 0.4 mm. The next layers should be applied only after the previous layer has dried. If you use a brush or roller, the average product consumption is approximately 500 ml per 1 m².

Here is the algorithm of actions:

Pour the liquid into a large container and stir well until it has a uniform consistency. To do this, you can use a special drill with a suitable tip. Experts advise setting the machine to medium speed so that the structure of the ceramic microspheres does not deteriorate during mixing.
Clean the surface to which paint will then be applied. Pre-treat with degreasing compounds. To do this, you can use a special solvent. If the surface is metal, then the rust should be removed.
Allow the surface to dry completely before applying paint. The first layer should be minimal in thickness, since it is a primer.
When using a roller or spray gun, you need to carefully handle joints and other places where there is no access. You'll have to use a brush.
It is recommended to do no more than 3 layers of paint for optimal results.
It will take about a day to dry completely. If you paint warm pipes, the paint will dry even faster.

Thermal paint Corundum will look beautiful, so it can be used not only as thermal insulation, but also as a finishing coating.

Conclusion

Thermal insulation paint Corundum is effective material, thanks to which it became very popular. It can be used not only as insulation, but also as a decorative layer on the facade. This coating has many advantages.
