Multi-layer, weatherable compositions and method of manufacture thereof

摘要

A weatherable composition comprising an upper layer that comprises a polymer selected from one of a cycloaliphatic polyester resin or an aliphatic polyamide resin and an additive composition comprising a hindered amine light stabilizer and a low volatility, hydroxyphenyl triazine or pyrimidine UV absorber; an intermediate layer that comprises a polymer system compatible with the polymer in the upperlayer, and optionally, an additive composition comprising TiO2, dyes, pigments and special effects additives; and a polymeric substrate, wherein the intermediate layer is disposed between and in intimate contact with the upper layer and the substrate. The composition finds utility in articles such as automotive parts.
