ABSTRACT:
Silicone rubber articles that are resistant to abrasion, permeation of gases and accumulation of dirt particles have an adherant coating on at least one surface of the article. The coating is derived from a peroxide-curable fluoroelastomer gum composition which contains (1) an epoxide compound in an amount sufficient to react with the acidic by-products generated during curing of the elastomer, and (2) an organic peroxide in an amount sufficient to achieve curing of the fluoroelastomer gum at elevated temperatures.
