Abstract: The present invention relates to a polycarbonate composite having an increased pencil hardness, comprising a polycarbonate substrate prepared from a thermoplastic aromatic (co)polycarbonate having a glass-transition temperature in the range of 160 to 210° C.; and a coating on said substrate, said coating being formed by curing a polysiloxane-based thermosetting coating material at a temperature in the range of 140 to 210° C. for 0.5 to 2 hours. The polycarbonate composite has a pencil hardness higher than H, as measured according to ASTM D3363. The present invention also relates to a method for producing said polycarbonate composite and an article comprising the same.

Abstract: The present application relates to a flame retardant polycarbonate composition and molded parts as well as articles made therefrom. The polycarbonate composition comprises the following components: an aromatic polycarbonate, a rubber-modified vinyl (co)polymer, an aromatic polyester, a reinforcement material, a phosphorus containing flame retardant; and a chain extender. The molded parts made from the polycarbonate composition according to the present invention have improved adhesion with a polyurethane-based coating system.
