Fuser member overcoated with fluorocarbon-silicone random copolymer containing aluminum oxide
A fuser member comprising a core and a layer overlying the core, the layer including a fluorocarbon random copolymer, a curing agent which cures the fluorocarbon random copolymer, the cured fluorocarbon random copolymer having subunits of:&#8212;(CH2CF2)x&#8212;, &#8212;(CF2CF(CF3))y&#8212;, or &#8212;(CF2CF2)z&#8212;,whereinx is from 30 to 90 mole percent,y is from 10 to 70 mole percent,z is from 0 to 34 mole percent;x+y+z equals 100 mole percent.The layer further including a particulate filler having aluminum oxide, having a total concentration in the layer of from 10 to 140 parts by weight per 100 parts of the fluorocarbon random copolymer, and alkaline earth metal oxides or alkaline earth metal hydroxides or combinations thereof; and siloxane polymer comprising one or more curable, silanol-terminated, polyfunctional poly(C1-6 alkyl)siloxane polymers.
