FIELD: chemistry.
SUBSTANCE: powder coating is obtained from a composition containing at least one binding material (A) from polyester resin with a hydroxyl functional group and at least one polyurethane resin (B) as a cross-linking agent containing blocked isocyanate groups. At least one binding material from the polyester resin (A) with a hydroxyl functional group and at least one polyurethane resin (B) have melting point of 60-180°C, specifically 60-160°C. The powder composition is deposited on a substrate and cured. The substrate can be metal, plastic, wood, paper or glass.
EFFECT: obtaining coatings with the required processing properties, specifically obtaining thin films and high flexibility combined with excellent mechanical coating properties.
