ABSTRACT:
The invention pertains to thermosetting powder paint compositions adapted to fuse and thermoset upon exposure to heat. The powder paint is based upon a one-component, self-curing polymeric binder comprising a thermosetting glycoluril copolymer containing methylol or alkoxy methyl glycoluril groups adapted to cross-link with reactive hydroxyl, carboxyl, or amide groups on the copolymer. The copolymer is produced by partial condensation of tetramethylol or tetra-alkoxy methyl glycoluril with units containing reactive hydroxyls, carboxyls, or amide groups.
