ABSTRACT:
A solid coating composition for use in powder coating and extrusion coating applications is disclosed. The coating composition contains about 70 to about 95% of a base resin, such as a polyester, and about 1 to about 50% of a low-to-medium molecular weight end-capped epoxy resin, and is essentially free of a bisphenol-A diglycidyl ether monomer. The solid coating composition is applied to a metal substrate in a powder coating or an extrusion process to provide a metal article having a composition film having a thickness of about 1 to about 200 microns. The metal articles can be used to package food and beverages.
