Use of release fluids or agents constituting hyperbranched polymers. The three-dimensional structure imparts characteristics that make the hyperbranched polymers useful in xerographic processes. The hyperbranched polymer release fluids or agents may be used with a fuser member having a substrate, an outer layer covering the substrate, and a release coating on the outer layer, wherein the release coating includes a hyperbranched polymer.

Release fluid compositions

A fuser member with a supporting substrate having an outer surface layer of a fluoroelastomer, and the fluoroelastomer outer surface layer is prepared by: a) dissolving a fluoroelastomer; b) adding and reacting a biphenyl compound and an amino silane having amino functionality to form a homogeneous fluoroelastomer solution; and c) subsequently providing a surface layer of the resulting homogeneous fluoroelastomer solution to the supporting substrate.

Fluoroelastomer members and curing methods using biphenyl and amino silane having amino functionality

A fuser member with a supporting substrate having an outer surface layer of a fluoroelastomer, and the fluoroelastomer outer surface layer is prepared by: a) dissolving a fluoroelastomer; b) adding and reacting a biphenyl compound and a monofunctional amine hydrocarbon compound to form a homogeneous fluoroelastomer solution; and c) subsequently providing a surface layer of the resulting homogeneous fluoroelastomer solution to the supporting substrate.

Polyetherimide-b-polysiloxane block copolymers are useful as surface layers for fuser and fixing members in various printing devices, including electrostatographic imaging systems and ballistic aerosol marking devices. Optionally, the polyetherimide-b-polysiloxane block copolymers are fluorinated, or include at least 50% by weight siloxane.

Fluoroelastomer compositions containing polyfunctional triaminopolysiloxanes having sterically large siloxane groups are disclosed. Compositions may be cured and are particularly suitable for use as surface release layers for fusing systems used in electrostatographic imaging systems.

Crosslinking of fluoropolymers with polyfunctional siloxanes for release enhancement

A process for making a multiple-layer elastomer-coated member, includes applying a coating of an elastomeric material to a supporting metallic substrate; and curing the elastomeric material by exposure to radiant energy in a radiant energy curing apparatus.

Process for making fuser and fixing members

A release agent having a polydimethylsiloxane and a fluorosurfactant other than a silicone glycol polymer, a perfluoroalkylsubstituted polyethylene glycol, or a perfluoroalkylsubstituted silane.

The present invention relates to electrostatographic fuser system members such as fuser rolls or belts having an outer surface layer comprising an interpenetrating polymer network comprising polytetrafluoroethylene and a cured polysiloxane elastomer, and a method for making such fuser system members.

Fuser members having improved thermal conductivity include an outer layer composed of elastomers and filler materials. The filler materials are oriented in the outer layer to provide directional thermal conductivity. Processes for forming the fuser members apply a liquid coating over a substrate and apply a magnetic field to the coating to orient the filler material. The coating is cured to retain the orientation of the filler material in the outer layer.

Fuser members having increased thermal conductivity and methods of making fuser members

A multilayered fuser member for fusing thermoplastic resin toner images to a substrate in a fuser system of the type wherein a polymeric release agent having functional groups is applied to the surface of the fuser member, the fuser member has a base support member, a thermally conductive silicone elastomer layer, an amino silane primer layer, an adhesive layer and an elastomer fusing surface comprising poly(vinylidenefluoride-hexafluoropropylene-tetrafluoroethylene) a metal oxide present in the fusing surface to interact with the polymeric release agent to provide an interfacial barrier layer between the fusing surface and the toner and substantially unreactive with the elastomer, the elastomer having been cured from a solvent solution with a nucleophilic curing agent soluble in the solution and in the presence of 4 parts by weight of inorganic base per 100 parts of polymer, the adhesive layer having been cured from a solvent solution of the above composition from which the fusing surface is cured and from about 5 to about 10% by weight of a coupling agent represented by the formula: ##STR1## where R can be an alkyl having 1 to 4 carbon atoms; R' can be an alkyl group having 1 to 7 carbon atoms; R' can be H, R or the acyl radical, ##STR2## X is a vinyl group or an alkenyl group or an alkyl, having 1 to 4 carbon atoms, substituted alkenylcarboxy group of less than 8 carbon atoms; and q is 1 or 2, k is 0 to 3, b is 0 to 2, a is 0 or 1, p is 0 to 20 and k+b+a=3.
