More Information
Summary:The present invention provides a water-repellent coating composition which enables easy removal of dirt while having good appearance due to high compatibility of a water-repellent component with other materials. The present invention provides a coating composition, comprising a siloxane group-containing polymer (A) and a crosslinking agent (B), wherein the siloxane group-containing polymer (A) is a block copolymer comprising an A block and a B block, and containing, in the A block, at least a structural unit derived from a siloxane group-containing vinyl monomer (a) and containing, in the B block, a structural unit derived from a hydroxyl group-containing vinyl monomer (b) and, as necessary, a structural unit derived from another vinyl monomer (c) copolymerizable with the vinyl monomers (a) and (b), and is a copolymer having a molecular weight distribution (Mw/Mn) of 2.0 or less and polymerized by living radical polymerization.
