A coating composition having a prolonged pot life is disclosed which is based on an organic polyhydroxy compound and an organic polyisocyanate in an organic solvent therefor. The composition contains 2-25% by weight of 2-methyl-2-propanol and/or 2-methyl-2-butanol. At least 0.8 equivalent of the monohydric alcohol is present per equivalent of the polyisocyanate to avoid premature chemical reaction with the formation of a polyurethane. |
