ABSTRACT:
A thermosetting in-mold coating for molded fiber-reinforced plastic parts is disclosed. The binder for the thermosetting coating is comprised of least one polymerizable epoxy-based oligomer having at least two acrylate groups and at least one copolymerizable ethylenically unsaturated monomer. The coating includes graphite and titanium dioxide which results in the gray color. The coating composition has good flow and coverage during molding, good adhesion, uniform color, good surface quality, and good paintability. The coating composition includes enough carbon black so that a 1.0 mil thick coating has a Ransburg conductivity meter reading of at least 165 units.
