ABSTRACT:
The present invention provides a low temperature curing coating powder composition comprising a mixture of a high gloss film-forming system and a low gloss film-forming system. Preferably, the high gloss film-forming system comprises a GMA (glycidyl methacrylate) resin, a curing agent, and a catalyst and forms a coating having a gloss greater than 80% measured at 60°. Preferably the low gloss film-forming system comprises a carboxyl terminated polyester, acrylic resin and a catalyst and forms a coating having a gloss less than 50% measured at 60°. The composition of the present invention provides coatings having a control gloss, which can range from a low to a high gloss and is useful for coating heat-sensitive substrates.
