ABSTRACT:
A method of preparing a composite of polyurethane bonded to the surface of a cured rubber substrate and the resulting composite. The method requires the rubber substrate to contain an hydroxyl terminated polybutadiene polyol. The method is practiced by first applying to a cleaned, cured rubber surface containing the polybutadiene polyol a coating of cyanuric acid followed by an additional coating of a phenol formaldehyde resin and then applying a liquid polyurethane reaction mixture which is cured to form the resultant composite. The invention is particularly directed to the preparation of a tire comprised of a polyurethane carcass applied to a cured rubber tread and to a tire comprised of a polyurethane tread applied to a cured rubber carcass.
