  • Paint for use on rubbers
    Patent number: 3979547
    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.
