Abstract
A method of making a fuser roller comprising: providing a fuser roller an outer layer comprising a fluorothermoplastic polymer; and annealing the outer surface of the outer layer through contact the outer layer by means of heat and pressure.
Claims10
A method of making a cylindrical member comprising:
- providing a cylindrical member comprising:
- a core member comprising a rigid outer surface;
- an adhesion promoter layer disposed on the outer surface comprising silane or epoxy silane coupling agent;
- a resilient layer disposed on said adhesion promoter layer;
- a primer layer, disposed on said resilient layer, comprising perfluoroalkoxy resin and trifluoroethylene-perfluoroethyl, vinyl ether-perfluoroethylene vinyl phosphate in a ratio of from 1 to 10 to 10 to 1 by weight of perfluoroalkoxy resin to trifluoroethylene-perfluoroethylvinyl ether-perfluoroethylene vinyl phosphate and;
- an outer layer disposed on said primer layer, said outer layer comprising a fluorothermoplastic polymer;
- and
- annealing an outer surface of the outer layer at a temperature of from 150° C. below the melting point to 100° C. above the melting point of the fluorothermoplastic polymer and a pressure of greater than 5 psig.
