Abstract
Process for obtaining lacquer coatings on metal substrates, characterized in that it comprises electrostatic powder coating of the substrates with powder coatings based on synthetic resins, based on polyurethanes obtained from aliphatic polyisocyanates and glycols with hydroxyl groups aliphatically linked and a molecular weight up to 250 simultaneously using polyhydroxy compounds with hydroxyl groups aliphatically linked with a molecular weight of 250 to 3000 and/or 0.5 - 15% by weight, based on the mass of polyurethane, of polyfunctional components with more than 3 hydroxyl groups and/or those with more than 2 isocyanate groups and a molecular weight of 700, and the subsequent heat treatment of the lacquer layer.
