Abstract
When polyurethane paint compositions are applied to natural or synthetic rubbers, as the paint composition dries and cures, the paint may 'orange-peel,' i.e. it wrinkles or beads without separating from the rubber. It has been found that by adding a small amount of a rubber to such a paint, such orange-peeling is prevented.
