摘要： Powder coating compositions based on epoxy functional copolymers and polycarboxylic acid curing agents are disclosed. The compositions have high epoxy content providing for excellent physical and chemical properties. In addition, the compositions are formulated such that they have a relatively low melt viscosity which provides for good flow and excellent coating appearance. The compositions are useful as clear coats.
