Abstract

A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorinated blend comprising a fluorinated copolymer surfactant and a fluorinated polydimethylsiloxane additive to form a coating solution, and b) providing the coating solution on the fuser member to form a fuser member coating, wherein the fluorinated copolymer surfactant comprises a copolymer selected from the group consisting of a fluorinated acrylate copolymer and a fluorinated polyether copolymer, and wherein said fluorinated polydimethylsiloxane additive comprises pendant fluorinated groups.
