A method for producing a conductive liquid silicone rubber composition having an excellent storage stability and suitable for molding a conductive silicone rubber article with an arbitrary speed of curing and with good reproducibility of arbitrarily selected hardness and volume resistivity. The method comprises mixing component (A) which is a mixture of a conductive filler with a liquid diorganopolysiloxane having two or more silicon-bonded alkenyl groups in one molecule, component (B) which is a mixture of a conductive filler with a liquid diorganopolysiloxane having two or more silicon-bonded alkenyl groups in one molecule and a volume resistivity different from that of (A), component (C) a platinum-based catalyst; and component (D) which is a cross-linker that comprises an organopolysiloxane having two or more silicon-bonded hydrogen atoms in one molecule.

The present invention relates to a silicone rubber composition for fixing roll service. More specifically, the invention relates to a silicone rubber composition for fixing roll service that is easily molded into a fixing roll as used in devices such as electrophotographic copiers, facsimile machines, and laser printers and that yields a fixing roll with an excellent mechanical strength and excellent toner release properties.

Silicone rubber composition for fixing roll service

A composition and method for treating fibers is based on an organopolysiloxane having at least one cyclohexylamino-substituted hydrocarbon radical directly bonded to a silicon atom. The composition and method provide non-yellowing fibers and a treatment agent that does not gel during use, such as when exposed to carbon dioxide and/or used to treat carbon fibers.

Fiber-treatment agent

A composition and method for treating fibers is based on a mixture of an organopolysiloxane having at least one amino-substituted hydrocarbon radical directly bonded to a silicon atom and a higher fatty carboxylic acid. The carboxylic acid reacts with the amino radicals to reduce yellowing and oxidation of the fiber treatment. The composition and method provide non-yellowing fibers and a treatment agent that does not gel during use, such as when exposed to carbon dioxide and/or used to treat carbon fibers.

Fiber-treatment organo-functional polysiloxanes agent composition

A composition and method for treating fibers is based on a mixture of an organopolysiloxane having at least one amino-substituted hydrocarbon radical directly bonded to a silicon atom and a carboxylic acid containing at least one ethylene oxide unit. The carboxylic acid reacts with the amino radicals to reduce yellowing and oxidation of the fiber treatment. The composition and method provide non-yellowing fibers and a treatment agent that does not gel during use, such as when exposed to carbon dioxide and/or used to treat carbon fibers.
