- 21 - ABSTRACT OF THE DISCLOSURE This invention is directed to a rubber skim stock and a product containing the skim stock having improved adhesion between a brassed or zinc coated metal member and contiguous rubber skim stock. The invention lies in the discovery that improved rubber-to-metal adhesion, and adhesion retention, can be obtained by adding to an otherwise conventional rubber skim stock composition appropriate amounts of cobalt propionate. In the practice of this invention, cobalt propionate is mixed into a rubber skim stock composition, which composition is brought into contiguous relationship with a brassed or zinc coated metal member in the unvulcanized composition followed by vulcanization to yield the end product.
