Abstract
Disclosed is a fuser member comprising a substrate, a layer thereover comprising a polymer, and, on the polymeric layer, a coating of a release agent comprising a mixture of (a) an organosiloxane polymer concentrate containing amino-substituted or mercapto-substituted organosiloxane polymers, wherein there are amino or mercapto functional groups on at least some of the polymer molecules of the concentrate, said concentrate having a degree of functionality of from about 0.2 to about 5 mole percent, said concentrate having a viscosity of from about 50 to about 500 centistokes; and (b) a nonfunctional organosiloxane polymer diluent, said diluent having a viscosity of from about 100 to about 2,000 centistokes; said mixture having a degree of functionality of from about 0.05 to about 0.4 mole percent, wherein the mixture has a viscosity of from about 100 to about 1,000 centistokes, and wherein the ratio by weight of concentrate to diluent is from about 1:2 to about 1:30.
