PROBLEM TO BE SOLVED: To provide a coating composition capable of forming a film which is excellent in slipperiness of water droplets even when fine dew condensation water is formed, and which can solve the occurrence of mold and freezing of the fin surface in winter. . SOLUTION: (A) a hydroxyl group-containing vinyl polymer, A coating composition capable of forming a water-slidable film containing (B) a siloxane polymer having specific functional groups at both ends and (C) at least one crosslinking agent component selected from a polyisocyanate compound which may be blocked and a melamine resin. And coating the coating composition on an aluminum fin material to form a water-slidable film as an uppermost film. |
