ABSTRACT:
A fuser member having a substrate, an outer layer with a fluoropolymer, and a release agent material coating on the outer layer, wherein the release agent material coating contains (a) a blend with a mercapto functional release agent having the following formula II:wherein A represents —R4—X, wherein R4represents an alkyl group having from about 1 to about 10 carbons, X represents —SH; R1and R2are the same or different and each is selected from the group consisting of an alkyl having from about 1 to about 25 carbons, an aryl having from about 4 to about 10 carbons, and an arylalkyl; R3is selected from the group consisting of an alkyl having from about 1 to about 25 carbons, an aryl having from about 4 to about 10 carbons, an arylalkyl, and a substituted diorganosiloxane chain having from about 1 to about 500 siloxane units; b and c are numbers and are the same or different and each satisfy the conditions of 1≦b≦10 and 10≦c≦1,000 d and d′ are numbers and are the same or different and are 2 or 3, and e and e′ are numbers and are the same or different and are 0 or 1 and satisfy the conditions that d+e=3 and d′+e′=3 and (b) a fluorinated silicone release agent having the following Formula I:wherein m is a number of from about 0 to about 25 and n is a number of from about 1 to about 25; x/(x+y) is from about 1 percent to about 100 percent; R1and R2are selected from the group consisting of alkyl, aryl, arylalkyl, and alkylamino groups; and R3is selected from the group consisting of alkyl, aryl, arylalkyl, alkylamino, a polyorganosiloxane, and a fluoro-chain of the formula —(CH2)o—(CF2)p—CF3wherein o is a number of from about 0 to about 25 and p is a number of from about 1 to about 25.
