The appointment of enameli KO-174, KO-198
The facade atmosphere enamel KO-174 is applied to a variety of structures, buildings, concrete products, and asbestosenta in addition to being used to decorate building facades. Additionally, painting machines, building equipment, and equipment can be made with this material. Paint is resistant to atmospheric conditions, so you can use it even in the bitterly cold Far North.
Because KO-174 uses premium pigments, it produces a coating that has a pleasing appearance. The resulting film’s characteristics are as follows:
- Excellent clutch with surfaces.
- Water resistance, impermeability for moisture.
- Frost resistance (up to 90 cycles of frost with defrosting).
- Thermal resistance is the ability to withstand temperatures up to +150 degrees.
- Lack of burnout under the sun.
Depending on the dye added, various colors of the product are produced. Shades of gray, blue, white, black, and green are possible. There are certificates of conformance for every batch.
The silicon used in Emal KO-198 is intended for different uses. According to the description, it is employed to shield the metal from chemicals and the effects of mineral groundwater:
- saline solution;
- nitric acid;
- of hydrochloric acid;
- sulfuric acid and t.D.
These qualities enable you to use this material to paint tanks, containers, tanks, and equipment used in the production of chemicals. Because of the product’s resistance to frost and corrosion, it is used on railroad platforms, bridges, reinforced concrete supports, and foundations. It is possible to use enamel in hot, tropical climates. The paint comes in red, brown, blue, yellow, black, white, and gray colors.
The appointment is the primary distinction between these hues. The second is meant to shield the metal from the action of aggressive substances and can withstand the work in a hot climate, if the first is used in cold climates for painting facades and structures. Both funds are created in compact, heavy-duty containers that can hold up to 50 kg.

Surface preparation
It is important to properly prepare the surface before using any of the listed paints. It is cleaned of fat, oil, dust, dirt, and rust in order to accomplish this. Additionally, old paint is cleaned. Depending on the product’s dimensions, either manual processing or a sandblasting machine is used for the preparatory work. Only the rust converter can be used if the surfaces are operated at temperatures up to +100 degrees. After all work has been completed, any remaining rust spots should be treated with a converter once more and thoroughly rinsed.
After completing the preparatory step, the base is completely dried and cleaned with degreasers (solvent, xylol). If the products are in an open area, this should be done six hours before painting; if they are indoors, it should be done a day later.
Preparation of the material
With the meshka, a wand, the enamel KO-174 is thoroughly mixed until the mass is homogeneous and free of sediment. After that, let the paint sit for ten minutes to allow the air bubbles to pop. The viscosity ought to vary based on the mode of application:
- for a roller, brush – 25–35 s;
- for spray gun – 17–25 s.
Solvents, xylol by 30% or less, are added if the viscosity is exceeded. The material is tightly closed during painting breaks, mixed once more, and allowed to stand for ten minutes.
The application technique and working viscosity of the enamel KO-198 are different from those of the previous one. It should have a viscosity of 12 to 20 seconds when applied with a spray gun. For breeding, the same solvents are employed. The remaining steps in the material preparation process are the same.
Staining technique
Using a roller or brush, pneumatic pollination is used to apply enamel KO-174. At least two layers of staining are applied, and the working temperature is between -30 and +40 degrees with a maximum humidity of 80%. Make sure the temperature is at least three degrees above the dew point if it is below that. When using a spray gun, a tool with a 1.8–2.5 mm nozzle is selected, the pressure is adjusted to 1.5–2.5 kgf/sq. cm, and the distance to the base is 20–30 cm.
Usually, a brush is used to paint the edges, ends, and seams. The metal must be stained in cross layers, with each layer needing to dry for 30 to 120 minutes, and the level of drying being monitored "for the cast." The drying time is increased by two to three times in below-freezing temperatures. The foundational materials are painted in three layers, with a two-hour drying time between each coat. Any surface requires at least 24 hours to fully dry.
There are not many variations in staining methods for Emal Ko-198. The only application technique that differs is the use of a spray gun (pneumatic spraying). parameters for temperature, humidity, and spray gun settings. Use the dipping method if the product is small. Only difficult-to-reach areas should be stained using the roller and brush. Additional crucial information regarding the work process:
- Metal products are painted on 2-3 cross layers, each is dried for 20 minutes, the final one is 4 hours at a temperature of +20 degrees, humidity up to 65%.
- The coating dries to the degree of 3 for 4 hours, completely polymerizes and hardens in 24 hours.
Safety requirements
Due to the solvents in their composition, both varieties of enamels are hazardous. The latter fall under the category of third hazards. Painting projects are best completed outside or with good ventilation. Gloves and respirators are required for workers. Gas masks should be worn when staining surfaces in pits, wells, and closed spaces.
Since enamel is flammable and easily ignited, it is crucial to shield it from heat and open fire. It is strictly forbidden to smoke close to the place of employment, and there should be tools available for putting out fires in the working area. Emalls are kept in storage between -40 and +40 degrees.
