Purpose and properties of compositions

The heat-resistant KO-815 varnish and the varnish with comparable qualities, KO-85, are examples of paintwork materials that belong to a particular group. These materials consist of a modified silicone resin complex on organic solvents. Their respective purposes are dictated by their properties; both are silicon of silicon. Both goods are components of heat-resistant paints, including:

  • EMAL CO-813 (the composition includes the KO-815 varnish);
  • enamel KO-814 (in the composition-LAK KO-85).

These varnishes improve other technical aspects of enamels and increase their resistance to heat. Additionally, a certain quantity of aluminum powder is added to the enamel to guarantee the required properties. The GOST 11066-74 standard specifies the properties and the application process.

Apart from being a part of paint compositions, KO-85 and KO-815 varnishes are employed to shield different surfaces from elements such as moisture, extreme heat and cold, rust, atmospheric phenomena, fuel and lubricants, and salt. When used, funds have demonstrated their worth the most.

  • concrete;
  • metals;
  • glass;
  • ceramics.

Enamel KO-813 and 814 is used to paint steel, cast iron, and other metal products that are utilized under particular circumstances. Materials that are used at temperatures between +400 and +500 degrees aid in protecting parts, equipment, and surfaces because of their increased thermal resistance.

Moreover, enamel can be used to stain cold-weather surfaces (down to –50 degrees). The paint is typically needed to apply to:

  1. Gas pipelines, oil equipment.
  2. Steam pipelines.
  3. Stoves in work and for waste burning.
  4. Exhaust pipes of the car.
  5. Separate interior engines compounds.

Characteristics of varnishes KO-815 and KO-85

KO-815 varnish is governed by stringent regulations and has several established characteristics. The primary indicators are as follows:

  • External data of the material-a homogeneous structure, color-brown, light yellow;
  • The proportion of the dry residue in the composition is 33–37%;
  • Conditional viscosity according to the device Viscimeter Z-246 at a temperature of +20 degrees-10–13 C;
  • acid number of varnish – up to 10 con/g;
  • drying period – at a temperature of +150 degrees – 1 hour.

These are the technical specifications of KO-85 varnish:

  • External data of the material-homogeneous texture, shade-light brown, light yellow;
  • the share of the dry residue in the composition is 15-17%;
  • Conditional viscosity according to the device Viscimeter Z-246 at a temperature of +20 degrees-12–17 s;
  • acid number of varnish – up to 3 con/g;
  • drying period – at a temperature of +20 degrees – 3 hours.

It is important to find the right varnishes and enamels for your project. In this post, we discuss the benefits and drawbacks of using KO-85 and KO-815 varnishes in addition to KO-813 and KO-814 enamels. By examining their distinct qualities, methods of application, and suitability, we hope to provide you with the information required to choose these products wisely for your painting projects. Knowing the subtleties of these brands can improve the longevity and quality of your finishes, whether you’re a seasoned professional or a do-it-yourself enthusiast, so your projects will last.

Surface preparation

Surfaces that are going to be processed need to be appropriately prepared. It needs to be cleared of:

  • spots of fat, technical oils;
  • any saline solutions;
  • dirt and dust;
  • remnants of old paintwork materials.

Use rags moistened with solvents, acetone, solvent, or similar substances to wipe products. After that, you should let the surface dry completely. Rust must be removed from the surfaces using sandpaper or sandblasting equipment. Per the international standard, the degree of purification ought to be at least SA2-2.5.

If the level of destruction is significant, the previous coatings are removed entirely. Only the damaged areas can be cleaned when there are partial chips and minimal coating destruction.

Within a 10-to 15-centimeter radius, the zones next to them are also processed. Paint and other materials need to be completely removed when the coating is damaged by 20% or more. In the same way, if the coating is thicker than 0.5 μm.

Before varnishing or staining, the product can be treated with a special tool if it operates in high-temperature environments and has specific requirements for resistance to rust. This primer, GF-021, greatly strengthens the resistance against corrosion.

Preparatory work with the material

The KO-85 and KO-815 varnishes need to be thoroughly kneaded until air bubbles cease to appear on the surface before staining. Six parts of aluminum powder are mixed with ninety-four parts of KO-815 varnish to create the enamel for the K-813. 100 parts of the KO-85 varnish are added to 5 parts of powder to prepare KO-814. Over the course of the following eight hours, both of the resultant paintjobs must be applied.

Should the viscosity surpass the standard, the substance needs to be diluted with toluene or other comparable solvents. Metering is done for at least ten minutes, or until the mass is perfectly uniform. Leave the material in the heat (+20 degrees) for a full day.

Application technique

Although it is acceptable to work at temperatures between -20 and +35 degrees, the ideal application conditions are around +20 degrees with less than 80% humidity. The product can be applied using a brush, roller, pneumatic sprayer, or airless sprayer. The spray nozzle’s diameter shouldn’t be larger than 1.8–2.5 mm. You can paint minute details by dipping.

In some situations, applying materials has the following characteristics:

  • when stained with a spray between it and the surface, 20-30 cm should remain;
  • Metal products are painted 2-3 times, from concrete, asbestos, cement, surface with plaster – 3 times;
  • Fund consumption – 110–180 g/sq. m.

Drying of coatings

For the Ko-813 agent, each layer should dry for two hours at +150 degrees, and for the KO-814 agent, it should dry for the same amount of time at +20 degrees. Every layer’s drying quality is examined "for Perepp." At 20 degrees, KO-85 varnish is dried for three hours, and KO-815 varnish is dried for one hour at +150 degrees.

When painted products are used in high-temperature environments, the surfaces finally harden. It is necessary to harden parts and equipment at a temperature of +250–+400 degrees for 20 minutes if they are going to be used in an aggressive environment with chemical agents.
