PURPOSE: A coating composition capable of forming a film having improved adhesivity to the surface of a substrate and wear resistance free from loss of material characteristics, consisting of terminal isocyanate group-containing urethane prepolymer, silicone oil, and a low-molecular polyol.

CONSTITUTION: A) 100 parts by wt. of an urethane prepolymer having terminal isocyanate groups obtained by reacting polyol with polyisocyanate is blended with B) 10 parts by wt. of silicone oil, and C) a low-molecular polyol as a curing agent. Polyoxypropylene glycol, polyethylene adipate, etc. may be cited as the polyol. Dimethyl silicone oil, fluoro silicone oil, etc. may be cited as the silicone oil; ethylene glycol, glycerol, etc., as the low-molecular polyol.
