ABSTRACT:
A thermosetting powder coating composition resistant to overspray incompatibility defects that comprises solid particulates of a uniform mixture of (a) a polyester resin having an average of two or more carboxyl groups, (b) a first crosslinker that is reactive toward the carboxyl groups of the polyester resin, (c) from 1% to 20% of a reactive acrylic copolymer having a weight average molecular weight of from 10,000 to 40,000, and (d) a second crosslinker that is reactive toward the reactive functionality of the acrylic copolymer is described.
