Abstract:
1. A process for producing a fuser member coating comprising: a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorine-containing polysiloxane additive, and a deflocculant to form a coating solution, and b) providing said coating solution on said fuser member to form a fuser member coating, wherein said fluorine-containing polysiloxane additive comprises pendant fluorinated groups and has the following Formula I: wherein m and n represent the number of repeating units and are the same or different, and wherein m is a number of from about 0 to about 25; n is a number of from about 1 to about 25; x/(x+y) is from about 1 percent to about 100 percent; R 1 and R 2 can be the same or different and are selected from the group consisting of alkyl having from about 1 to about 18 carbon atoms, arylalkyl groups having from about 1 to about 18 carbons, amino groups, and alkylamino groups having from about 1 to about 18 carbons; and R 3 is selected from the group consisting of alkyl having from about 1 to about 18 carbons, arylalkyl having from about 1 to about 18 carbons, a polyorganosiloxane chain having from about 1 to about 300 repeat units, and a fluoro-chain of the formula —(CH 2 ) o —(CF 2 ) p —CF 3 wherein o and p represent the number of repeating units and are the same or different, and wherein o is a number of from about 0 to about 25, and p is a number of from about 0 to about 25.
