ABSTRACT:
A thermosetting acrylic powder coating composition contains an acrylic copolymer of a methacrylic acid and at least one other monoethylenically unsaturated monomer, a crosslinking agent capable of reacting with carboxylic acid groups, a blend of an ultraviolet light stabilizer and an ultraviolet screener capable of preventing degradation of the coating by ultraviolet light and a flow control agent. Preferably, the composition is nonpigmented and provides a clear, glossy, and durable film useful as the clear coat of a clear coat/color coat automobile finish.
