Abstract: An organopolysiloxane composition which has improved adhesion and is curable at an elevated temperature in the presence of atmospheric moisture comprising:(a) An organopolysiloxane having an average of at least two hydroxyl groups per molecule;(b) an organosilicon compound containing at least two hydrolyzable groups per molecule which is capable of reacting with the hydroxyl groups of the organopolysiloxane;(c) an organohydrogenpolysiloxane containing at least one silicon-bonded hydrogen atom per molecule;(d) a platinum catalyst; and(e) if desired, a condensation catalyst.The resultant composition is generally heated to an elevated temperature to form an elastomer.

Abstract: A process for preparing a one-component organopolysiloxane composition which comprises heating a catalyst which is capable of promoting the addition of silicon-bonded hydrogen to aliphatically unsaturated groups in the presence of an organopolysiloxane having aliphatically unsaturated groups and/or a filler at an elevated temperature and thereafter adding an organosilicon compound having silicon-bonded hydrogen to the mixture after it has cooled. The resultant composition, which can be stored at room temperature can be crosslinked by heating to a temperature of about 100.degree. C. or more.

Abstract: Silicone elastomers having thermally conductive properties which comprise an organopolysiloxane having Si-bonded aliphatically unsaturated groups, an organohydrogenpolysiloxane having Si-bonded hydrogen atoms, a catalyst capable of promoting the addition of Si-bonded hydrogen to Si-bonded aliphatically unsaturated groups and from about 30 to 95 percent by weight of filler, based on the weight of the composition, of which at least 10 percent by weight of the filler is silicon nitride particles.

Abstract: Radiation polymerizable compositions containing organopolysiloxanes having an average of at least one nitrogen-containing group per molecule linked to a silicon atom through an Si--N or Si--O--N linkage and a photo-induced free radical source.

Abstract: Platinum-styrene complexes are prepared by reacting a platinum halide with styrene or substituted styrenes in the presence of a basic material for a sufficient amount of time to form a complex having more than one and less than four gram atoms of halogen per gram atom of platinum.These platinum-styrene complexes may be used to promote the addition of organosilicon compounds having at least one .tbd.SiH group per molecule to a compound containing aliphatic unsaturation.

Abstract: This invention relates to a composition containing (A) a bridging agent, (B) a hydrocarbon oil and (C) an organopolysiloxane fluid, in which the organopolysiloxane fluid (C) is immiscible with hydrocarbon oil (B) in the absence of bridging agent (A) and a process for treating organic fibers therewith. The bridging agent is obtained from the reaction of a hydrolyzate of a diorganodihalosilane with a primary, secondary or tertiary alcohol, in which the hydrocarbon group of the alcohol is a saturated or unsaturated branched chain or an unsaturated linear chain and contains from 12 to 28 carbon atoms.
