ABSTRACT:
A method for bonding unvulcanized fluorinated elastomers to vulcanized non-fluorinated elastomers comprising exposing the vulcanized elastomer to a fluorinating agent; applying a conventional fluorinate elastomer adhesive to the treated vulcanized elastomer; contacting the adhesive-coated portion of the vulcanized elastomer with the unvulcanized fluorinated elastomer; and curing in situ the fluorinated elastomer. Sulfur tetrafluoride is a preferred fluorinating agent.
