ABSTRACT:
This invention is directed to a rubber skim stock and a product containing the skim stock having improved adhesion between a brassed 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 sulfides of copper.
In the practice of this invention, a sulfide of copper is mixed into a rubber skim stock composition, which composition is brought into contiguous relationship with a brassed metal member in the unvulcanized composition followed by vulcanization to yield the end product.
