First, a backing is provided having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer further comprises a compound represented by the formula: R 1 represents a divalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. R 2 represents a monovalent or divalent poly(dimethylsiloxane) moiety. X represents -NH- or a covalent bond. R f represents a perfluorinated group having from 3 to 5 carbon atoms. y is 1 or 2. Second, an adhesive layer is disposed onto the first silicone release layer. Third, the adhesive layer is exposed to E-beam radiation within a process chamber containing oxygen to provide a crosslinked adhesive layer. An adhesive article made by the method and the compound are also disclosed.

Abstract: A graft co-polymer is provided comprising a vinyl polymeric backbone with grafts of siloxane monomers and monomers containing an anchoring group. Such co-polymers are well suited for coating metal molds. The siloxane groups provide release to the metal mold, while the anchoring groups provide durability to the coating. The durability and release characteristics may be varied by the number of grafts of each monomer and the molecular weight of the siloxane moiety. The co-polymers may be coated from water or organic solvents.
