摘要：

The synthesis and characterization of a new type of low temperature curing powder coating is described. The type of materials used were mixtures of an amorphous methacrylate-functional prepolymer and crystalline acrylate and methacrylate monomers. The introduction of a crystalline component in an amorphous resin mixture was shown to markedly reduce the melt viscosity and thus enhance the flow properties of the powder coating. Curing experiments showed the advantage of using photoinitiation compared to thermal initiation. The reaction was much faster and the problem with oxygen inhibition could be avoided.
