摘要： An isocyanate-curing coating material is disclosed which essentially consists of (A) an agent formed of a hydroxyl group-containing polymer having a weight average molecular weight in the range of 1000-20000 and (B) a polyisocyanate compound as a curing agent containing at least three isocyanate groups in the molecular unit thereof and having a weight average molecular weight in the range of 400-3000 and incorporating (A) the agent and (B) the curing agent in such amounts that the isocyanate groups in (B) the curing agent amounts to 0.5-2 equivalent weights per equivalent weight of the hydroxyl group in (A) the agent. A method for spray coating the isocyanate-curing coating material is also disclosed which comprises the steps of mixing (A) the agent with (B) the curing agent in a coating device, heating the resultant mixture therein to a temperature in the range of 35-80.degree. C., and spraying the hot mixture directly on a given object with the coating device.
