Publication number: 20110159222Abstract: A composition comprising a fluorocarbon thermoplastic random copolymer having the subunits of: —(CH2CF2)x-, —(CF2CF(CF3))y-, and —(CF2CF2)z-, wherein x is from 1 to 40 or 60 to 80 mole percent, z is greater than 40 to no more than 89 mole percent, and y is such that x+y+z equals 100 mole percent; wherein the fluorocarbon thermoplastic random copolymer is crosslinked with an organic primary amine. The composition may be formed by curing an aqueous coated composition of the fluorocarbon thermoplastic random copolymer and a water soluble organic primary amine, such as triethylenetetraamine (TETA). A fuser member comprises a substrate having an outer substrate surface, and an outer layer disposed over the outer substrate surface where the outer layer comprises such a composition.Type: ApplicationFiled: December 28, 2009Publication date: June 30, 2011Inventors: Jiann-Hsing Chen, Jerry A.

Pneumatically adjustable apparatus for coating toner fusing belt substrate and method for using same
Patent number: 7560140Abstract: An apparatus for enabling the uniform application of a layer of a coating composition to a tubular substrate includes a shaft, and upper and lower circular rim members of equal diameter that are concentrically attached to the shaft. A pneumatically inflatable tube disposed on each circular rim member has an outer diameter that is variable with changes in its internal pressure. A first flexible cylindrical sheet in contact with the inflatable tubes has parallel edges that form a first slit sufficiently wide to permit movement of the first sheet in response to pressure variation in the tubes. A second flexible cylindrical sheet surrounding the first cylindrical sheet has parallel edges that form a second slit sufficiently wide to permit movement of the second sheet also in response to pressure variation. The second slit is laterally displaced from the first slit, and the second cylindrical sheet has a diameter nearly equal to the specified diameter of the substrate.Type: GrantFiled: October 3, 2008Date of Patent: July 14, 2009Assignee: Eastman Kodak CompanyInventors: Jiann-Hsing Chen, Robert A.
