Purpose:
Modified primer paint is intended for the anti-corrosive and protective protection of steel, cast iron, and sheet metal structures. It is suitable for renovating metal household equipment elements. It can also be used as an undercoat for protecting wooden and wood-like elements and for coating some plastics.
Characteristics:
A suspension of pigments and fillers in an alkyd resin solution in organic solvents with the addition of pigments, auxiliary agents, and anti-corrosion substances. Available in various colors.
Product properties:
Korchem is compatible with the coatings of many products. The product has good application properties and is intended for both external and internal painting of steel structures, construction machinery, agricultural machinery, and other surfaces. It is recommended especially where anti-corrosion resistance properties and good adhesion to the substrate are necessary. It can be used for painting work using various application techniques - brush, roller, pneumatic or hydrodynamic spraying. The resulting coating exhibits very good adhesion to the substrate, good elasticity, and mechanical resistance.
