Formbeschichtungen mit verbesserter Leistung

摘要

The hardness and appearance of an in-mold coating for a molded article of cured unsaturated polyester are improved by the addition of melamine and/or benzoguanamine to an unsaturated polyester powder coating composition and subjecting the modified powder coating to a molding temperature of from 126.5-171 DEG C and a pressure of from 4.48 to 13.8 MPa for 1 to 12 minutes. From 5 to 40 parts of the melamine and/or benzoguanamine per hundred parts by weight of the coating resin is preferably used.
