摘要:
Fuser members and processes are provided for crosslinked fluorocarbon elastomer surfaces containing a fluorocarbon elastomer and a non-amino crosslinker together with methods for providing a crosslinked fluorocarbon elastomer surface on a fuser member supporting substrate which include mixing together an acid acceptor, an emulsifier, water, and non-amino based crosslinker with a latex fluorocarbon elastomer.
摘要:
Fluoroelastomer compositions containing polyfunctional triaminopolysiloxanes having sterically large siloxane groups are disclosed. Compositions may be cured and are particularly suitable for use as surface release layers for fusing systems used in electrostatographic imaging systems.
摘要:
Disclosed is a fusing release agent comprising the reaction product of a primary- or secondary-amino-functionalized polyorganosiloxane oil and a low molecular weight, non-sterically-hindered aldehyde or ketone.

摘要:
Disclosed is a composition comprising a crosslinked product of a liquid composition which comprises (a) a fluorosilicone, (b) a crosslinking agent and (c) a thermal stabilizing agent comprising a reaction product of (i) a cyclic unsaturated-alkyl-group-substituted polyorganosiloxane, (ii) a linear unsaturated-alkyl-group-substituted polyorganosiloxane, and (iii) a metal acetylacetonate or metal oxalate compound. The crosslinked fluorosilicones can be employed as intermediate or outer layers of electrostatographic fuser members, electrostatographic intermediate transfer belt materials and the like. They are useful in applications wherein materials possessing desirable release characteristics, surface energies, electrical characteristics, oil resistance properties, or solvent resistance properties exhibited by fluorosilicone elastomers are desirable. They are also useful in applications wherein fluorosilicones are exposed to high temperatures, since the stabilizing components reduce the generation of toxic effluents such as trifluoropropionaldehyde and formaldehyde, which can form when methyl-methyl crosslinking of the polymer occurs, and increase temperature stability.
