  This invention provides a novel storage stable, heat curable, coating composition comprising (a) a ketoxime blocked polyisocyanate, (b) a polyol containing 2-4 terminal OH groups, (c) at least one ethylenically unsaturated monomer, oligomer or prepolymer of the formula: wherein R is H or CH3, R is an organic moiety and n is 1 and preferably at least 2, (d) a free radical thermal initiator for (c), and (e) a deblocking and curing catalyst for (a). The reaction between (a) and (b) in the composition results in a thermoset material which is believed to form an interpenetrating network with the resulting thermoset from (c) on the thermal curing. The coating composition which is airless sprayable, storage stable and can be cured at low temperatures (about 80 - 120°C) provides a coating having good adhesion to metal surfaces with good abrasion resistance and good corrosion protection.
