ABSTRACT:
Disclosed is a composition for the improvement of the adhesion and adhesion retention between conventional rubber skim stock compositions, utilized in the manufacture of tires, conveyor belts, hoses and the like, and metallic reinforcement cords such as brassed steel. The invention composition is prepared by incorporating an inorganic salt of cobalt or nickel and a rosin-derived resin into the rubber stock prior to contacting the metallic reinforcement. Tests conducted with brass-plated and zinc-plated steel cords showed improved metal adhesion and metal adhesion retention with use of the rubber skim stock of this invention when compared to existing formulations.
