Claims7
A thermosetting powder coating composition having improved optical properties comprising a carboxylic acid group-containing acrylic, a beta-hydroxyalkylamide curing agent, and about 0.1 percent to about 15 percent of a fatty acid hydroxyalkylamide group-containing material selected from the group consisting of lauramide diethanolamine, acetamide diethanolamine, capramide diethanolamine and stearamide diethanolamine.
A thermosetting powder coating composition having improved appearance properties comprising a coreactable mixture of a carboxylic acid group-containing acrylic, a beta-hydroxyalkylamide curing agent, and from about 0.1 percent to about 15 weight percent by weight based on the weight of the acrylic, of a fatty acid hydroxylalkylamide group-containing material selected from the group consisting of lauramide diethanolamine, acetamide diethanolamine, capramide diethanolamine and stearamide diethanolamine.
