An in-mold coating composition comprising A. a polyurethane polyacrylate or polymethacrylate which is the reaction product, substantially free of unreacted -HCO radicals of (1) an organic diisocyanate; (2) a hydroxy alkyl acrylate or methacrylate; (3) an organic diol, selected from alkylene diols, alkylene diol esters and polyesters; alkylene diol ethers and polyethers; B. copolymerizable alpha-, beta-ethylenically unsaturated monomer; C. an initiator for addition polymerization; D. fillers;
Claim 3
Dependent Claim
47 words
A composition as claimed in claim 1 wherein the molar ration of said organic diol to said hydroxy alkyl acrylate or methacrylate is 0.15 to 0.5 and the amount of said organic diisocyanate is sufficient to develop a NCC/OII ratio of 0.9 to 1.0 in the composition.
Claim 4
Dependent Claim
17 words
A composition as claimed in claim 1 or 2 wherein the said organic diisocyanate is toluene diisocyanate.
Claim 5
Dependent Claim
24 words
A composition as claimed in claim 1, 2 or 3 wherein the said organic diol is difunctional polyester of adipic acid and diethylene glycol.
Claim 6
Dependent Claim
18 words
A composition as claimed in claim 1, 2 or 3 wherein the said organic diol is polypropylene glycol.
Claim 7
Dependent Claim
38 words
A composition as claimed in any one of claims 1 to 5 wherein 0.075 to 5.0 parts by weight of the slid polyurethane polyacrylate are provided for each part by weight of the said ethylenically unsaturated copolymerizable monomer.
Claim 8
Independent Claim
114 words
A method for producing a coated, molded, fiber-reinforced thermoset plasticsarticle comprising producing a fiber-reinforced, thermoset plastic article in a matched metal mold; opening the said mold after the article has attained its intended shape; introducing into the open mold a composition as claimed in any one of claims 4 to 6 closing the mold and thereby spreading the said composition over at least one surface of the said article; retaining the mold in the closed condition at a molding temperature until the said article is further cured and the said composition is cured; opening the mold and recovering a molded, fiber-reinforced thermoset plastic article having an adherent coating over at least one surface thereof.
Claim 9
Dependent Claim
62 words
A method as claimed in claim 7 wherein said fiber-reinforced thermoset plastics material is made from a composition comprising: A. an unsaturated polyester resin B. a copolymerizable monomer for the unsaturated polyester resin C. fillers D. a catalyst for the condensation polymerization of the ursaturated polyester resin with the copolymerizable monomer E. a mold release agent; and F. glass fiber reinforcing material.
Claim 10
Dependent Claim
14 words
A molded article produced by a method as claimed in claim 7 to 8.
