Composition and technical characteristics of enamel KO-174, scope of application

KO-198 or KO-174 enamel is used for protective and decorative painting of various surfaces. These paints and varnishes contain organosilicon resins, which form a hard film after application to the base and drying. The coating layer protects the surface from negative climatic factors. The service life of painted objects is more than 10 years.

Composition and characteristics

All organosilicon glazes are marked with the letters "K" and "O". The number “1” means that paint and varnish products are used for exterior work (façade). These paints contain organic resins which make the coating resistant to abrasion. In addition, this enamel dries quickly in the open air. After painting, a coating is formed that is resistant to high (low) temperatures and water.

KO-174

In terms of its composition, KO-174 type enamel is a combination of modified pigments and organosilicon resin fillers. Used for exterior work (for protective and decorative painting). The paint is completely ready to use. Available in a variety of colors (white, red, black and other colors).

Before painting, it must be thoroughly mixed, too thick can be diluted with R-5, 646, thinner or xylene.

It is applied by brush, roller or spray on a prepared and primed base. After drying, a semi-matte or matte solid film forms on the surface. The coating has such properties as hydrophobicity, frost resistance, heat resistance. It is recommended to apply the enamel in 2 layers.

Features of the KO-174:

• dries in 2 hours;
• adheres to any base;
• forms a strong and durable coating with a service life of more than 10 years;
• applied at a temperature of -15 (-20) degrees, if there is no ice and frost on the base to be painted;
• can be used at temperatures from -40 to +40 degrees;
• painting can be carried out in regions with any climate;
• forms a coating resistant to temperature extremes, frost, precipitation, salt spray;
• does not fade in the sun;
• withstands temperatures up to +150 degrees;
• is a toxic and flammable material.

KO-198

KO-198 also contains organosilicon resin, as well as pigments, fillers and additives. It is mainly used for painting various metal surfaces. Used for protective and decorative purposes. Available in basic colors (gray, black, white, brown and others).

Features of KO-198:

• dries quickly (in just 20 minutes);
• adheres to metal;
• forms a strong, hard film that protects the surface from moisture and acid;
• does not let water through (protects metal from corrosion);
• does not fade in the sun;
• enamel is applied at temperatures from -30 to +40 degrees;
• painting on metal is carried out in 2-3 layers, concrete and plaster surfaces - in 3 layers;
• can withstand temperatures of +300 degrees.

Coloring technique

It is advisable to let the mixed and diluted paint stand for ten minutes so that all the air bubbles come out.When using a spray gun, a thinner solution is prepared. Large flat surfaces are painted with a roller or spray gun. Dye the edges and ends with a paintbrush.

Analogs

In addition to KO-174 and KO-198 enamels, other paints containing organosilicon varnish are produced. For example, KO-168. This enamel is used for exterior (façade) and interior work. With the help of KO-168 you can paint the facades of buildings, concrete walls, plaster and metal surfaces. KO-88, KO-813 and KO-814 enamels are used to protect and paint metal. These paints are used to paint a variety of metal surfaces exposed to high temperatures.
