Fluorocarbon random copolymer for use in toner release layer

In a process for forming a fluoroelastomer composite material for use in preparing an image member containing a substrate, a curable fluorocarbon elastomer is combined with preformed polysiloxane particles in an organic solvent, thereby forming a composite mixture. Milling the composite mixture produces a uniform coating dispersion of the fluoroelastomer composite material in the organic solvent.

Process for forming fluoroelastomer composite material containing polydialkylsiloxane particles

A fuser member whose outermost layer comprises a fluorocarbon-silicone interpenetrating network, comprising: (a) a first polymer comprising a fluorocarbon elastomer; (b) a second polymer selected from a curable polyfunctional poly(C alkyl)siloxane polymer; a curable polyfunctional poly(C alkyl)arylsiloxane polymer; and combinations thereof; and (c) a functionalized polydimethylsiloxane containing amine groups.

Fluorocarbon-silicone interpenetrating network useful as fuser member coating

A fuser member having a support metallic core and a layer of material formed over the metallic core, the layer includes composite material, including a high molecular weight reactive polyfunctional poly(C alkyl)siloxane polymer; a cross-linked poly(dialkylsiloxane) incorporating an oxide, wherein the poly(dialkylsiloxane) has a weight average molecular weight before crosslinking of about 5,000 to 80,000; and a silane crosslinking agent.

Fuser member having composite material including polyalkyl siloxane

A roller for use in a fusing assembly for receiving a polymeric release agent including a core and multiple layers secured over the core; and the multiple layers including at least one outer layer formed of a silicone mixture which absorbs the polymeric release agent and has toner release properties, and an intermediate layer formed of a silicone mixture selected so that its swelling in 1000 cts poly(dimethylsiloxane) is less than 1% by weight.

Fuser assembly with controlled polymeric release agent swell intermediate layer

A material for coating an imaging member comprising: a crosslinked poly(dialkylsiloxane), zirconium silicate and optional T-resin.

Polysiloxane based fuser member containing zirconium silicate and a silicon T-resin

A method for preparing silicone particles having an average particle size of 6 microns or less, said method comprising the following steps. First, a multifinctional vinyl terminated polysiloxane is mixed with a hydride terminated polysiloxane, surfactant, and polymerization catalyst under ambient conditions. This mixture is then dispersed in water under ambient conditions. The dispersion is the heated to cure the silicone. Afterwards the dispersion is broken and the particles are washed.

Fluorosilicone interpenetrating network and methods of preparing same

The toner fuser roll of the present invention, which is characterized by good thermal conductivity and resistance to degradation by release agents in addition to excellent wear properties, is capable of producing toner fused images with desirably high gloss. In accordance with the invention, the fuser roll comprises a cylindrical core and a base cushion layer comprising a condensation-cured poly(dimethylsiloxane) elastomer formed on the core. A barrier layer that comprises a cured fluorocarbon polymer and includes a particulate filler overlies the cushion layer. Overlying the barrier layer is a highly smooth outer surface layer comprising an addition-cured poly(dimethylsiloxane) elastomer and having a roughness value, R,, no greater than about 10 microinches. Further in accordance with the invention is a process for forming the just described toner fuser roll. In addition to its capability of producing a highly smooth PDMS outermost layer, the process is environmentally advantageous, employing coating formulations containing volatile organic compounds at levels below those mandated by environmental regulations.
