DEVELOPMENT OF POLYURETHANE PAINT METALLIC EFFECT WITHOUT CLOUD DEFECT

The article presents tests results of the metallic paint system. The system consists of high solid corrosion protection primer and dual-component topcoat with a metallic gloss effect (RAL 9006). The paint system properties were examined after the conditioning period. The measurements included an adhesion test, a flexibility test, hardness test, gloss test, a corrosion resistance test and a humidity resistance test. The article focuses on “cloud” defect in metallic paints because of grain distribution in topcoat and also presents results of the product developed in our company.
