Abstract: A fuser member for fixing toner to a recording medium having a fluoropolymer non-stick topcoat on a compliant silicone rubber baselayer bonded to a metallic insert is provided. The fluoropolymer is adhered to the silicone rubber baselayer using a primer of a blend of silane and a polyamide resin. The primed silicone baselayer is preheated in an infrared oven to remove low molecular weight fractions.

Abstract: A multi-layer roll having a thin fluoropolymer top coat on an elastomeric base layer bonded to a substantially rigid insert is provided. The top coat is formed by placing a thin non-self supporting fluoropolymer sleeve about the insert, or wrapping extruded fluoropolymer film about the insert which is placed in a mold sleeve and positioned in a book mold to hold the membrane in place. Liquid or flowable elastomer is injected into the space between the insert and flexible top coat at a point downstream of where the top layer is held in position between mold elements to prevent wrinkling. The mold is then heated to cure the elastomer.

Abstract: A multi-layer roll having a thin fluoropolymer top coat on an elastomeric base layer bonded to a substantially rigid insert is provided. The top coat is formed by placing a thin non-self supporting fluoropolymer sleeve and about the insert, or wrapping within extruded fluoropolymer film about the insert which is placed in a mold sleeve and positioned in a book mold to holds the membrane in place. Liquid or flowable elastomer is injected into the space between the insert and flexible top coat at a point downstream of where the top layer is held in position between mold elements to prevent wrinkling.

Abstract: A micro-compliant roll having a PTFE top layer on a silicone rubber baselayer bonded to a metallic insert is provided. The roll with PTFE top coat is heated under pressure to a temperature below the PTFE crystalline melting point and quenched to provide a compliant top layer having crystallinity of no more than about 70 percent. The PTFE top layer is applied by adhering a fibrillated PTFE membrane to a silicone rubber baselayer using a primer of a blend of silane and a polyamide resin, or wrapping the PTFE film about an insert with end spiders placed in a sleeve mold and liquid or flowable elastomer is injected into the space between the insert and PTFE membrane.

Abstract: A fuser member for fixing toner to a recording medium having a fluoropolymer non-stick topcoat on a compliant silicone rubber baselayer bonded to a metallic insert is provided. The fluoropolymer is adhered to the silicone rubber baselayer using a primer of a blend of silane and a polyamide resin. The primed silicone baselayer is preheated in an infrared oven to remove low molecular weight fractions. A primer is applied to the prebaked rubber and completely dried before applying the fluoroelastomer topcoat by spaying.

Abstract: A method of forming a fuser roll by disposing a substantially uncured fluoroelastomer composition which is substantially free of metal containing material on a substrate, and curing the fluoroelastomer material. The fluoroelastomer has at least about 23.4 mole percent hexafluoropropylene and can be cured by electron beam treatment, fugitive base treatment or by the use of blocked/hindered bases.

Abstract: A fluoroelastomer composition free of metal or metal containing compounds, such as metal, metal alloys, metal salts or metal oxide suitable for the upper layer of a fuser roll which does not require the use of mercapto functional active release agents to prevent offset is provided. The fluoroelastomer compositions contain at least 23.4 mole percent hexafluoropropylene. They can be cured by electron beam treatment, fugitive base treatment or by the use of blocked/hindered bases.
