Heat -resistant enamels of the series – description
Sillar-organic paints, varnishes, and enamels are significantly more heat resistant than other paints and coatings. The process of synthesizing a silicon compound macromolecule with highly stable bonds between silicon and oxygen atoms yields heat-resistant material. Additionally, the required qualities result in a range of targeted additives:
- anti -corrosion substances;
- acrylic varnishes;
- carbide layers;
- epoxy resins;
- ethyl cellulose, etc.D.
Special pigments are added to the mixture to get the desired color. They also have a heat-resistant base, so even at very high temperatures, the color remains vibrant. Since they protect the metal’s surface from corrosion, colors are typically applied to it. However, if used in an aggressive environment, enamel can be used on brick and concrete.
The enamels have the following characteristics:
- withstand heating up to +600 degrees;
- racks to the action of steam, moisture, atmospheric precipitation, sunlight, a number of chemicals (chlorine and t.D.);
- do not require heat -blooding;
- have excellent clutch indicators with surfaces;
- easily applied;
- can be used in external and internal work;
- After complete drying, they are non -toxic;
- Provide decorative qualities.
These days, companies that produce and process oil and gas use a lot of these paints and varnishes. In addition, they color heating pipes, furnaces, reinforced concrete buildings, fireplaces, ventilation systems, and power plants and marine enterprises.
Differences of the enamel of the series
There are a number of enamels produced in the series that share many similarities but also differ greatly in terms of their properties and descriptions.
KO-8101
At temperatures between -60 and +600 degrees, anti-corrosion enamel KO -8101 is primarily used to paint automobile exhaust systems and to coat pipelines, furnaces, and heating systems. The aim is to give the products an appealing appearance while providing rust protection.

- Beige, etc.D.
Since the tool only has one component, there is no need for extra preparation before use. Additionally, priming prior to enamel operation is not required.
KO-8104
Similar in scope, this tool is used to prevent metal products from corroding and can withstand temperatures as high as +600 degrees for a shortened period of time. Paint is therefore most frequently applied to pipelines in mechanical engineering. Additionally, a method can be used to process products made from stone, brick, concrete, and other mineral materials. Product colors include blue, yellow, green, gray, red-brown, and blue.
KO-8111
Heat pipes, gas turbines, generators, and steam can all be safeguarded with this instrument. The capacity of KO-8111 to maintain its properties in an aggressive environment and not react negatively to changes in chemistry over an extended period of time sets it apart from other silicon enamels. Furthermore, this substance can be used on the exterior in extremely cold temperatures.
KO-870
Although it is more resistant to water action than the previous enamels, it is essentially identical. As a result, it can be applied in situations where there is a moisture product contact and higher than usual air humidity. The device has demonstrated its efficacy when used outdoors, where surfaces are exposed to the direct effects of precipitation. The range of applications includes equipment, generators, gas and steam turbines, and fences made of concrete and brick. The material comes in a range of colors, just like analogs.
KO-868
It is applied in situations where the surface is impacted by both high temperatures and high humidity. Brick, concrete, and artificial stone can all be treated with the product; however, metal serves as the primary protective material. The most typical applications for enamel are:
- pipelines;
- construction equipment;
- tanks;

Any enamel should have a uniform, semi-dummy, matte, or even film appearance. Peeling and cracking should not occur when exposed to temperature changes of -60 to +600 degrees.
Surface preparation
There is a general instruction on surface preparation for all colors that are described. Preparatory actions like these are taken in order to increase adhesion with the base:
- Peel the painted product of dirt, dust, salts, fat and other pollutants;
- remove the entire existing rust, as well as a paint that is poorly gripped with the surface (all or individual sections);
- Cleaning is made to the extent of ST3, SA2-2.5 according to the standards;
- Before staining work, degrease the base with solvent or xylolom, start painting no later than 6 hours in an open area, in a day in a closed room.
The primary requirement for a high-quality outcome is having a base that is entirely dry and clean; only then will the material lie evenly and adhere well.
The enamels belonging to the KO-8101, KO-8104, KO-8111, KO-870, and KO-868 brands are highly prized for their remarkable resilience to harsh weather conditions and protective attributes. Every variety provides special advantages: Excellent adhesion and weather resistance characterize KO-8101, superior corrosion protection is offered by KO-8104, flexibility and chemical resistance distinguish KO-8111, heat resistance is a selling point for KO-870, and strength and aesthetic appeal are combined in KO-868. These characteristics ensure dependable and long-lasting performance, making them perfect for a range of industrial and protective applications.
Preparation of the material
The preparation guidelines for Emali KO-8104, KO-8111, KO-868, and KO-870 are the same. The material needs to be well-kneaded before using in order to achieve homogeneity and remove the precipitate. It’s important to release air bubbles after they haven’t started staining for ten more minutes. Before beginning any work, control measurements are made, and the following indications should be present:
- viscosity during pneumatic pollination-17-25 s;
- viscosity when spraying by an airless way-30-45 C;
- viscosity for applying with a brush, roller-25-35 s.
The indicator is measured at near room temperature (+20 degrees) using the BI-4 Viscimeter with a 4 mm nozzle. If the viscosity is exceeded, xylolol and orthoxilol are used to thin the enamel, but not more than 30%. When it is necessary to make adjustments in a small-scale project, the details are easily overlooked. After that, remix the material and let it sit for ten minutes.
The sole distinction in the preparation of Ko-8101 paint is the indicator of the working viscosity during pneumatic pollination. Under the same starting circumstances, it ought to be between 15 and 17 C. Solvent or xylol are used in breeding.
Coloring
For the enamels KO-868, KO-870, KO-8104, and KO-8111 Here’s how the staining procedure is done. Using an airless sprayer, roller, brush, and pneumo-pollution, application is done in two layers. Applying money is possible in an electrostatic field. Working conditions:
- humidity – up to 80 %;
- temperature -from -30 to +40 degrees;
- When working in the cold, it is important to ensure that the surface temperature is at least 3 degrees above the dew point (this is required to prevent the appearance of ice crusts, hoarfrost);
- The distance from the nozzle of the spray and the base during pneumo-pollination is 20-30 cm, the pressure is 1.5-2.5 kgf/sq. cm, nozzle diameter-1.8-2.5 mm.
Epoxy is applied with a brush to edges, seams, and hard-to-reach areas. Two to three layers of paint are applied to the metal surfaces (crossroads), and each layer is allowed to dry for 30 to 120 minutes (the precise duration varies based on the temperature; the base is checked "for the cast"). Time can increase by two or three times in a subzero environment. Items composed of concrete, cement, and plaster surfaces are painted in three layers.
Drying of the final coating is made for at least a day at a temperature of +20 degrees, final hardening is observed when using products. It is possible to make hot drying – first withstand the surfaces at room temperature for half an hour, then increase the temperature by 3.5 degrees/minute, and so on within an hour. If it is supposed to use products under the influence of oils, gasoline, saline solutions, other substances, hot drying should be made for 15-20 minutes at 250-400 degrees. The thickness of the finished coating is usually 40-50 μm. The number of layers is determined by the application by the total thickness of the coating. Put into work, transport products after painting work in 3 days.
There are some variations in the drying procedure for enamel KO-8101. Dry the coatings for just two hours at +20 degrees, not for 24 hours as with the others. When heated products are operated, full hardening takes place. The hot drying method is used in a similar way.
Safety
When handling paint of any kind, precautions need to be taken. Because the materials contain solvents, they are toxic. The latter fall into the third hazard class and are within the 150/50 mg/cube m working range of the MPC. Staining products in open spaces with adequate ventilation is preferable. Put on gloves or special pastes to protect your hands, and cover your face with a respirator.
Work cannot be done in wells, pits, or closed spaces without proper ventilation and personal safety equipment. It is best to use anti-gas gas in these circumstances. The high fire hazard of enamels is also determined by solvents, so the work area should be free of heat sources and flames. When putting out a fire, foam, sand, and finely poured water are used.
