Abstract: A two-pot vapor curable acrylic polymer formulation which is crosslinkable with a diisocyanate crosslinking agent. The solvent used is water free and has a good evaporation rate in an acrylic urethane polymer system. The preferred acrylic polymer has a molecular weight below 10,000 and a content of 15 to 50% by weight of an hydroxy unsaturated acrylic monomer. The remaining acrylic or unsaturated monomers are selected to provide the final polymer with a glass transition temperature in the preferred range of -10.degree. C. to 30.degree. C. These two-pot formulations exhibit high initial hardness as well as forming tough coatings within 24 hours of curing.
