ABSTRACT:
A polyalkylene rubber substrate is coated with a reaction product of a mixture of organic polyisocyanate and a polycaprolactone polyol having a molecular weight of 250 to 3500. The mixture from which the reaction product is prepared contains the organic polyisocyanate and polycaprolactone polyol in a ratio which provides between 0.8 and 1.35 hydroxyl groups per isocyanate group. The coating composition is dried after it has been applied to the substrate.
