Abstract: A fuser member comprised of a supporting substrate comprising an outer layer of a volume grafted elastomer, which is a substantially uniform integral interpenetrating network of a hybrid composition of a fluoroelastomer and a polyorganosiloxane, said volume graft having been formed by dehydrofluorination of said fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerization by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerization initiator; and wherein said outer layer contains a reactive metal oxide in an amount of from about 2 to about 7 weight percent.

Abstract: Metal sheets having a layer of a cured polyvinylidene fluoride paint on the metal surface and a layer of a cured fluorinated ethylene vinyl ether paint on the polyvinylidene fluoride paint exhibit excellent weathering properties, have a gloss of 25 to 80%, and may be bent to a sharp angle without cracking of the coating. Such sheets are particularly useful in the preparation of metal-resin composite laminates, because they do not experience thermal blocking during the lamination step.
