Abstract
This invention provides a curable fluoroelastomer composition comprising: (A) a fluorine-containing polymer or a blend of fluorine-containing polymers each comprising interpolymerized units derived from one or more fluorine-containing ethylenically unsaturated monomers; (B) an aromatic polyhydroxy crosslinking agent; (C) at least one organo-onium compound; and (D) a monohydroxyfunctional phenol. The compositions provide for a method of improving scorch safety of curable fluoroelastomer compositions.
