Abstract
Compression molded pigmented door skins fabricated by compression molding a pigmented, curable, unsaturated polyester sheet molding compound containing a co-curable unsaturated monomer, a low profile additive, and a microvoid-reducing thermoplastic polymer, exhibit uniform stainability while maintaining a low linear thermal coefficient of expansion. Such door skins are suitable for preparing wood grain textured exterior insulated doors which exhibit minimal thermal deflection when exposed to interior/exterior temperature differentials, even at eight foot door heights. The doors may be stained without first applying a seal coat.
