ABSTRACT:
A fiber glass reinforced plastic can be in-mold coated utilizing a free radical peroxide initiated thermosetting composition of at least one polymerizable epoxy based oligomer having at least two acrylate groups, at least one copolymerizable ethylenically unsaturated monomer, at least one copolymerizable monoethylenically unsaturated compound having a --CO-- group and a --NH.sub.2, --NH-- and/or --OH group, and other conventional components such as at least one zinc salt of a fatty acid, at least one accelerator, at least one filler, and the like. The thermosetting compositions of the present invention utilize a very low or nil amount of an adhesion agent such as a polyvinyl acetate and unexpectedly achieves better flow and good coverage at reduced coating weights.
