摘要:
The disadvantages associated with using a platinum-catalyzed hydrosilylation reaction to prepare sponge products from curable organosiloxane compositions can be overcome by microencapsulating the platinum-containing catalyst in a thermoplastic organic or organosilicone polymer.

A method of preparing a silicone elastomer coated cloth having a surface coating of silicone resin is described. The coated cloth is elastic and pliable with a surface which has superior dirt resistance. The cloth is first coated with an addition-reaction-curing silicone elastomer composition which uses a platinum system catalyst or with an organic peroxide-curing silicone elastomer composition. The uncured elastomer layer is then coated with a silicone resin composition of the addition-reaction-curing type which uses a platinum system catalyst and has a molar ratio of organic groups to silicon atoms of 0.8 to 1.8. The silicone elastomer composition layer and the silicone resin composition layer are then heat cured simultaneously.

摘要:
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.

A silicone rubber sponge composition, a silicone rubber sponge, and a process for making the silicone rubber sponge. The silicone rubber sponge composition comprises (A) 100 parts by weight organopolysiloxane gum described by average structural unit RaSiO(4−a)/2, where R is a monovalent hydrocarbon group or haloalkyl and a is 1.8 to 2.3 and having a viscosity of 1,000,000 mPa·s or above at 25° C., (B) 1 to 400 parts by weight inorganic filler, (C) 0.01 to 50 parts by weight hollow thermoplastic resin particles, (D) 0.1 to 10 parts by weight liquid compound with a boiling point above room temperature, and (E) a curing agent in an amount sufficient to cure the composition.
摘要:
A silicone rubber composition that yields silicone rubber whose durometer can be freely reduced without a concomitant reduction in the mechanical properties of the silicone rubber. The reduction in durometer is achieved by controlling the concentration of an organosiloxane having hydrogen substitution on terminal silicon atoms.
