PURPOSE:To obtain a composition providing a coating compound having excellent durability and flexibility, having high utility value applicable to places having difficulty in recoating, by blending a specific fluororesin with a flexibility imparter and a curing agent. CONSTITUTION:(A) 100 pts.wt. hydroxyl group-containing soluble fluororesin having 0.05-2.0dl/g intrinsic viscosity in tetrahydrofuran at 30 deg.C is blended with (B) 5-50 pts.wt. flexibility imparter containing hydroxyl group as a curing site, 2-10 curing sites per molecule and further an alkylene chain of polymerized ethylenic unsaturated groups and having 50-10,000 molecular weight in the molecule and (C) 1-100 pts.wt. curing agent (e.g. melamine curing agent or urea resin curing agent) to be reacted with hydroxyl group of the component A and the curing site of the component B. |
