摘要:
Fluoroelastomer surfaces and a method for providing a fluoroelastomer surface on a supporting substrate which includes dissolving a solid fluoroelastomer in a solvent, adding an amino silane in order to effect coupling and crosslinking and to form a resulting homogeneous fluoroelastomer solution, and subsequently providing a layer of the homogeneous fluoroelastomer solution to the supporting substrate is provided herein.
摘要:
Volume grafted elastomer surfaces and a method for providing a volume grafted elastomer surface on a supporting substrate which includes dissolving a fluoroelastomer in a solvent, adding a nucleophilic dehydrofluorinating agent, preferably an amino silane which acts as both a dehydrofluorinating agent and curing agent, a polymerization initiator and a polyorganosiloxane in amounts sufficient to effect formation of a volume graft elastomer, optionally adding an additional amount of amino silane as a curative in order to ensure complete curing of the volume grafted elastomer, and subsequently providing a layer of the homogeneous volume grafted elastomer solution to the supporting substrate are provided herein.
摘要:
A fuser member comprised of a supporting substrate comprising an outer layer of a volume grafted elastomer, which is a substantially uniform integral interpenetrating network of a hybrid composition of a fluoroelastomer and a polyorganosiloxane, said volume graft having been formed by dehydrofluorination of said fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerization by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerization initiator; and wherein said outer layer contains a reactive metal oxide in an amount of from about 2 to about 7 weight percent.
摘要:
An electrographic imaging member comprising a supporting substrate and an outer layer of a volume grafted fluoroelastomer comprised of a substantially uniform integral interpenetrating or crosslinked network of a polyorganosiloxane grafted fluoroelastomer.
摘要:
A method for providing a crosslinked fluorocarbon elastomer surface on a fuser member supporting substrate, which includes mixing together an acid acceptor, an emulsifier, water, and non-amino based crosslinker with a latex fluorocarbon elastomer, and the crosslinker is a diepoxy or disilylalkoxy-based crosslinker, or a combination thereof.
摘要:
A fuser component useful in electrostatographic machines, having a substrate, and thereover a silicone rubber layer having the crosslinked product of at least one platinum catalyzed addition curable vinyl terminated polyorganosiloxane, aluminum oxide fillers, iron oxide fillers, a crosslinking agent, and having an optional outer fluoroelastomer layer.
