    摘要： The room temperature-curable coating composition comprises, as the resinous vehicle thereof, a copolymer prepared by the radical copolymerization of a ternary monomeric mixture composed of (A) 20-80% by weight of an alkyl (meth)acrylate, e.g., methyl methacrylate, (B) 10-78% by weight of an oligomeric organopolysiloxyanylalkyl (meth)acrylate, e.g., 1,1,1,3,5,5,5-heptamethyl-3-(3-methacryloxypropyl) trisiloxane, and (C) 2-30% by weight of an organosilane compound having at least one hydroxyzable group and a radical-polymerizable unsaturated group, e.g., 3-methacryloxypropyl trimethoxy silane. The coating composition gives a cured coating film having outstandingly high weatherability and resistance against ultraviolet light, water and chemicals in comparison with conventional room temperature-curable acrylic resin-based coating compositions.
