ABSTRACT:
The present invention discloses a fuser roller composition that contains a fluorocopolymer, an aliphatic ketone organic solvent, metal oxide particles, and a benzyltriphenylphosphonium phenolate salt curing agent. To this composition is added a sufficient amount of 4,4′-(hexafluoroisopropylidene) diphenol to extend a time at which viscosity of the composition rises above a predetermined level.
