Abstract
Abstract This provides an anti-icing coating composition comprising as vehicle components: (a) a copolymer having hydroxyl, or hydroxyl and a reactive group other than hydroxyl and comprising as essential monomer components a fluoroolefin and a vinyl monomer having hydroxyl and copolymerizable with the fluoroolefin, (b) a silicone compound represented by the formula ##STR1## wherein n is an integer of 6 to 300, k is an integer of 0 to 6, h is 0 or 1, m is an integer of 0 to 6, j is 1 or 2, and Y is a) hydroxyl, or b) a group reactive with the hydroxyl or the reactive group in the copolymer (a) and selected from among (i) carboxyl, (ii) epoxy and (iii) a monovalent or bivalent group containing one or two free isocyanate groups, and (c) a polyisocyanate compound.
