Description of the material

Environmentally friendly paint with anti-corrosion qualities is called Emal K-42. When surfaces need to be shielded from moisture and rust while being in contact with food items, enamel is frequently utilized. The material is produced in 1, 15, and 50 kg containers, with each kilogram costing roughly 300 rubles. Co-42T material is a subtyping that shares similar areas of application and technical characteristics.

Zinc powder, ethylcate binding components, copolymers of vinyl chloride, vinyl acetate, and plasticizers make up the composition of the two-component material. The paint is a matte gray color. The material doesn’t release any hazardous compounds into the liquid, is waterproof, and can withstand high humidity or submersion in water. Paint can be applied even at -30 degrees below zero, as the product is resistant to short-term temperature fluctuations between -60 and 300 degrees.

Areas of application

The materials’ description and application area are specified in the instructions. KO-42, KO-42T provides a human-safe coating that is resistant to corrosion, which is why the material is used for the following applications:

  • protection of tanks, tanks, barrels for storing drinking water;
  • applying on containers for storing and transporting products, food fluids and raw materials.

Utilizing cold zinc for the material’s application enables us to safeguard river and maritime vessels that are currently being built. Even at high temperatures, this technique aids in preventing contact with the base. This enables you to stop chemical pollutants from escaping.

Differences of KO-42 from KO-42T

Heat resistance is the primary distinction. The enamel KO-42T is most frequently used to paint hot drinking water supply pipes because of its long resistance to temperatures as high as +100 degrees. When contact with either warm or cold water is anticipated, Emal K-42 is typically utilized.

Technical specifications

The following technical attributes should be present in both of these materials, per the available certificates of conformance:

  • The coating is gray, matte, without extraneous inclusions, even, smooth;
  • viscosity according to the Viscimim of the BI-4 at a temperature of +20 degrees-18–32 C;
  • The proportion of the dry residue is 68–72%;
  • drying time to the degree of 3 at +20 degrees – 20 minutes;
  • adhesion of the film – 1 point;
  • elasticity on the bend – 3 mm;
  • strength during impact according to the U-1-50 cm device;
  • resistance to the direct effect of water at +20 degrees – 96 hours;
  • layer consumption – 250–330 g/sq. m;
  • layer thickness – 30–40 microns;
  • The number of layers is 4.

Ethyl alcohol is added to paint in a volume equal to 5% of the mass of paint as a solvent. The coating will function for at least three years, provided that the requirements for applying and completing four layers are met. At room temperature, the paint will remain viable for six hours following the connection of the powder with the base.

Boilers, exhaust systems, and industrial machinery are just a few examples of the metal surfaces that Paint KO-42’s adaptable, heat-resistant coating is perfect for shielding from high temperatures. KO-42 is well-known for its toughness and ability to withstand corrosion, which guarantees reliable operation even in challenging conditions. To apply this paint, follow these simple steps: prime the surface, apply the primer, and carefully coat the area. This ensures the best possible adhesion and protection. Users can achieve a dependable, high-quality finish and increase the longevity of their equipment by adhering to the recommended procedure.

Preparation for application

Sandpaper or sandblasting are used to remove old coatings, rust, mud, and oil from metal surfaces. If required, apply xylol after toluene has weakened the surface. This should be completed and left for no longer than six hours before staining.

Additionally, the material must be ready. To do this, slowly and in portions, one part of the base is connected to two parts of zinc powder, interfering with the last. The paint is thoroughly blended to achieve a consistent texture. After that, you should give it 30 minutes for the air bubbles to go away. If alcohol is not available, acetone can be used to bring the material’s viscosity to the desired level. Like alcohol, acetone is present in trace amounts—up to 5%.

The application process can be carried out using the pneumatic spraying method, which requires a working viscosity of 17–25 from. When using a brush and roller, the viscosity should be between 25 and 35 s.

Instructions for the use of paint

Only after the surface has completely dried can staining be done. Operating temperatures range from +15 to +40 degrees, with up to 80% humidity. When pneumatic pollination is used, the apparatus’s nozzle should be placed 10–20 cm from the base, have an air pressure of 1.5–2.5 kgf/sq. cm, and have a diameter of 1.8–2.5 mm. Usually, the brush is only used to stain areas that are difficult to reach, ends, edges, and seams.

Three to four cross layers are painted on the base, and the intermediate driers are left at room temperature for 20 to 30 minutes. The drying process takes two to three times longer in negative temperatures. After seven days, complete polymerization and the emergence of all protective qualities are accomplished. The goods can only be used after the specified amount of time.

Packaging, transportation, storage

GOST 9980-4 applies to markings, while GOST 9980-3 governs packaging. The tool is transported in designated containers that are appropriately marked, and it falls under the third category of hazards. Every mode of transportation—air, rail, water, and road—is employed. One year from the date of release is the shelf life. Keep paint in an airtight container at a temperature between -50 and +40 degrees, shielding it from moisture and sunlight.
