Abstract
The present invention relates to a thermoset powder coating composition and method of application. The coating includes a copolymer having a reactive functionality selected from the group consisting of epoxy, carboxy, and hydroxy functionalities and mixtures thereof, a suitable crosslinking agent capable of reaction with the reactive functionality on the copolymer, and an aliphatic or aromatic crystalline, hydroxyl containing compound having a melting point of between 30.degree. C. and 150.degree. C. and a flow control agent. The powder coating is a pigmented or clear coat powder composition applied over a primer layer.
