Abstract:
A fuser member whose outermost layer comprises a fluorocarbon-silicone interpenetrating network composition, comprising:a fluorocarbon elastomer; about 10-150 parts of a curable siloxane polymer; about 1-60 parts of a functionalized polydimethylsiloxane of the formula: whereinR and Râ€² are independently alkyl; haloalkyl; aryl; alkylene; or arylene; all having 1 to 10 carbon atoms; X and Y are functional groups having an active hydrogen selected from â€”NH2, or â€”NRâ€³H where Râ€³ is C(1-6) alkyl or aryl; and where n, m and o are positive integers including zero such that n+m+o provides a number average molecular weight in the range of about 1000 to 20,000; about 1-10 parts of a fluorocarbon curing agent; about 1-10 parts of a fluorocarbon-curing accelerator; about 4-30 parts of an acid acceptor filler; and about 0-30 weight percent of an inert filler; all based on 100 parts fluorocarbon elastomer, wherein the total siloxane polymer content of the fluorocarbon-silicone interpenetrating network composition is about 30.1 weight percent-about 36.7 weight percent.
