An FRP molding can be in-mold coated using a one-component free radical peroxide initiated composition of (a) a polymerizable oligomer selected from the group consisting of (1) a polyurethane based oligomer having at least two acrylate groups, (2) an epoxy based oligomer having at least two acrylate groups and (3) a polyester based oligomer having a plurality of internal ethylenically unsaturated groups and mixtures of the same, (b) a copolymerizable ethylenically unsaturated monomer, (c) a zinc salt of a fatty acid having at least 10 carbon atoms, (d) an accelerator for the peroxide initiator and (e) polyvinyl acetate. Optionally and desirably the composition additionally contains (f) a mono- unsaturated compound having a -CO- group and a -NH2, -NH- and/or -OH group, (g) a liquid copolymerizable compound having from 2-4 vinyl groups, being free of urethane, cycloaliphatic and aromatic groups and having a molecular weight of up to about 1500, (h) a calcium salt of a fatty acid having at least 10 carbon atoms and (i) a filler. |
