Claims18
A fuser system member comprising a supporting substrate with a basic metal oxide-free outer surface layer consisting essentially of the reaction product of a fluoroelastomer, a polymerization initiator, a polyorganosiloxane and an amino silane.
A fuser system member comprising a supporting substrate with a basic metal oxide-free outer surface layer and wherein said outer layer consists essentially of the reaction product of a fluoroelastomer, an amino silane, a polymerization initiator and a polyorganosiloxane, wherein the amino silane content is from about 0.5 to about 10 percent by weight based on the weight of said fluoroelastomer.
A fuser system member in accordance with claim, 1, wherein the supporting substrate is selected from the group consisting of aluminum, copper, and steel.
A fuser system member comprising a supporting substrate having an outer layer comprising a basic metal oxide-free volume grafted elastomer, said volume grafted elastomer prepared by:
- a) dissolving a fluoroelastomer;
- b) adding and reacting an amino silane as a dehydrofluorinating agent and a curing agent in an amount of from about 0.5 to about 10 weight percent based on the weight of fluoroelastomer;
- c) adding a polymerization initiator, a polyorganosiloxane and optionally adding an additional amount of amino silane to form a homogeneous volume grafted elastomer;
- and
- d) subsequently providing at least one layer of the homogeneous volume grafted elastomer of c) to said supporting substrate.
A fuser system member comprising a supporting substrate having an outer layer comprising a basic metal oxide-free volume grafted elastomer, said volume grafted elastomer prepared by:
- a) dissolving a fluoroelastomer;
- b) adding a dehydrofluorinating agent, a polymerization initiator and a polyorganosiloxane;
- c) adding and reacting an amino silane in an amount of from about 0.5 to about 10 percent to effect curing, thereby forming a homogeneous volume grafted elastomer;
- and
- d) subsequently providing at least one layer of the homogeneous volume grafted elastomer of c) to said supporting substrate.
A fuser system member comprising a supporting substrate with an outer surface layer consisting essentially of the reaction product of a fluoroelastomer, a polymerization initiator, a polyorganosiloxane and an amino silane, wherein the amino silane is of the formula NH.sub.2 (CH.sub.2).sub.n NH(CH.sub.2).sub.m Si((OR).sub.t (R').sub.w), wherein n and m are numbers from about 1 to about 20;
- t+w=3 and R and R' are an aliphatic hydrocarbon having from about 1 to about 20 carbon atoms or an aromatic group having from about 6 to about 18 carbon atoms.
