Abstract
In accordance with the disclosure, a fusing member is provided comprising, in order, a base member, a cured liquid silicone rubber substrate layer, an amino silane, and an anhydrous solvent containing adhesive layer. The fusing member further comprises a fluoroelastomer fusing surface topcoat layer including poly (vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene).
Claims4
A fusing member comprising, in order:
- a base member;
- a cured liquid silicone rubber substrate layer;
- an amino silane and an anhydrous solvent containing adhesive layer;
- a fluoroelastomer fusing surface topcoat layer comprising poly(vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene);
- wherein said solvent is selected from the group consisting of a methanol and a ketone;
- said solvent content of said adhesive layer is from about 5% to about 10%;
- said amino silane is comprised of curative (N-(2-aminoethyl)-3-aminopropyltrimethoxysilane);
- and,
- wherein an adhesion between said topcoat layer and said substrate layer includes a pull force in a range exceeding 2.25 lb/in and up to 3.37 lb/in.
6 more elements
A fusing member comprising:
- a base member;
- a liquid silicone rubber substrate cured about said base member;
- a solution of (N-(2-aminoethyl)-3-aminopropyltrimethoxysilane) and an anhydrous solvent formed into an adhesive;
- said adhesive deposited as a layer onto said substrate;
- said adhesive layer topcoated with a fluoroelastomer layer;
- said anhydrous solvent content of said adhesive layer is from about 5% to about 10%;
- wherein a weight of said adhesive layer is from about 2.5 g/1440 cm2 to about 4.0 g/1440 cm2;
- said anhydrous solvent is selected from the group consisting of a methanol and a ketone;
- and,
- wherein an adhesion between said fluoroelastomer layer and the cured said substrate includes a pull force in a range exceeding 2.25 lb/in and up to 3.37 lb/in.
7 more elements
A fusing member comprising:
- a base member;

- a diluted solution of (N-(2-aminoethyl)-3-aminopropyltrimethoxysilane) in anhydrous methanol forming an adhesive;
- said adhesive applied as a layer onto said substrate;
- said adhesive layer topcoated with a fluoroelastomer layer;
- wherein said anhydrous methanol content of said adhesive layer is from about 1% to about 30%;
- wherein a weight of said adhesive layer is from about 2.5 g/1440 cm2 to about 4.0 g/1440 cm2 ;
- wherein applying said adhesive includes a dwell time from about 15 min. to about 180 min.;
- and,
- wherein an adhesion between said fluoroelastomer layer and the cured said substrate includes a pull force in a range exceeding 2.25 lb/in and up to 3.37 lb/in.
