ABSTRACT:
Polyurethane resins and polyurethane coating compositions are provided which exhibit enhanced resistance to weather. The resins comprise the reaction product obtained from reacting a polyol with 1,6,11-undecanetriisocyanate. The resin composition herein disclosed is readily adapted for use in either a one component-heat curing system or in a two component-polyol hardening system. In the one component system, the isocyanate group of the isocyanate compound is blocked by a blocking agent so as to ensure stability of the coating at room temperature. After application, the coating resin is heated to effect reaction of a hydroxyl group from the polyol with an isocyanate group to cause hardening of the film. In the two component system, the polyol-pigment liquid, liquid "A", is mixed with the trifunctional isocyanurate compound (above noted) and solvent, liquid "B".
