Abstract

A thermosetting powder paint coating containing a polymeric binder comprising a polyester graft acrylic copolymer and a low molecular weight crystalline polyester. The coatings can be pigmented or non-pigmented. The polyester-graft-acrylic copolymer can be self-crosslinking by the inclusion of beta-hydroxy ester groups or crosslinked by an external crosslinker.
