PROCESS FOR MOLD COATING OF ARTICLES OR MOLDED PARTS IN POLYESTER RESINS OR VINYL ESTERS REINFORCED WITH GLASS FIBERS, COMPOSITION FOR CARRYING OUT THIS PROCESS AND THE PRODUCTS THUS OBTAINED

摘要

An FRP molding can be in-mold coated using a one-component peroxide initiated composition of (a) a liquid crosslinkable composition having an average molecular weight of up to about 5,000, having a plurality of polymerizable ethylenic double bonds, being essentially free of active hydrogen atoms or being essentially free of isocyanate groups and (b) a material selected from the group consisting of (I) a polyisocyanate and (II) the reaction product of an excess of equivalents of a polyisocyanate and an ethylenically unsaturated compound having -NH2, -NH- and/or OH groups, said reaction product being free of active hydrogen atoms.
