Multilayer Fuser Rolls having Fluoropolymer coating on a Compliant Baselayer
A fuser member of 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 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 spraying.
Fluoroelastomer Coated Fuser Roll
A fuser member for applying heat and pressure to fuse toner to a recording medium which does not require use of mercapto functional release agents has a surface of fluoroelastomer material including vinylidene fluoride and at least about 23.4 mole percent hexafluoropropylene.
