A coating composition curable with a vapourized catalyst formed by mixing a poly-isocyanate cross linking agent with an acrylic polymer in a water free solvent, having a good evaporation rate in an acrylic urethane polymer system, said acrylic polymer having a molecular weight below 20,000, preferably less than 10,000 and a content of 15 to 50% by weight of an hydroxy unsaturated monomer and the remaining monomers being selected to provide the final polymer with a glass transition temperature in the range of -40<o>C to 55<o>C. |
