Abstract
The present teachings disclose a surface coating composition. The surface coating composition includes fluorine containing particles, aerogel particles and positive tribocharging particles. The surface coating is useful as the release layer for fuser members.
Claims20
A coating composition comprising fluorine containing particles, aerogel particles and positive tribocharging particles.
A method of making a fuser member, comprising:
- obtaining a fuser member comprising a resilient layer disposed on a substrate;
- spray coating a powder comprising a composition of fluorine containing particles, aerogel particles and positive tribocharging particles on the resilient layer to form a coated layer;
- heating the coated layer to a temperature of from about 260° C. to about 380° C. to form a release layer.
A fuser member comprising:
- a substrate;
- and
- an outer layer disposed on the substrate, wherein the outer layer comprises a fluorine containing matrix having dispersed therein aerogel particles, wherein the aerogel particles comprise from about 0.1 weight percent to about 10 weight percent, and fumed alumina particles, wherein the fumed alumina particles comprise from 0.1 weight percent to about 5 weight percent of the outer layer and wherein the fuser member has a G75 surface gloss ranging from about 5 ggu to about 70 ggu.
