Abstract: A method of restoring electrical distribution cafes that have lowered performance due to treeing is carried out by (i) supplying the interstices of stranded aluminum conductor portions of such cafes with a restoration fluid comprising an alkoxysilane or mixture of alkoxysilanes selected from aromatic functional alkoxysilanes, alkylalkoxysilanes, amino functional alkoxysilanes, epoxy functional alkoxysilanes, fluoro functional alkoxysilanes, vinyl functional alkoxysilanes, or methacrylate functional alkoxysilanes; and (ii) adding a sulfidosilane, a mercapto functional alkoxysilane, a phosphonated silane, or mixtures thereof, to the restoration fluid to improve the corrosion resistance of the aluminum, as it comes into contact with corrosive agents at elevated temperatures.

Abstract: A silicone MQ resin based composition provides the oil industry with Fluid Loss Control (FLC) additives for water based drilling muds which are non-damaging. The composition is capable of achieving zero fluid seepage through filter cake, and a short build time for the initial filter cake, while not reducing the return flow of oil from producing formations. The composition is stable in saturated salt at 120° C. and elevated pressures. The composition comprises solid particles of silicone resin with a glass transition temperature more than 70° C., and it contains solid particles of silicone resin with a particle size distribution in which ( ) at least 90 volume percent of solid particles of silicone resin have an average major axis diameter of 40 ?m or less than 40 ?m, and (ii) at least 10 volume percent of solid particles of silicone resin have an average major axis diameter of 2 ?m or less.

Abstract: A curable silicone-based coating composition, curable to a flexible coating at a coat weight of up to 15 g/m2 when cured, comprises an organopolysiloxane polymer having at least two silicon-bonded olefinically unsaturated hydrocarbon substituents, alkoxy groups or hydroxyl groups and having a degree of polymerization of no more than 150, a cross-linking organosilicon material having at least 3 silicon-bonded reactive groups and a catalyst. The coating composition optionally contains non-reinforcing filler but contains no more than 3% by weight of reinforcing filler. The coating is preferably used on a textile fabric that has an elastomeric coating on it, and reduces friction. It is particularly useful for airbags.

Abstract: A curable silicone coating composition obtained is by mixing ingredients comprising: (A) a polyorganosiloxane having at least 2 silicon-bonded alkenyl groups per molecule, (B) a polyorganohydrogensiloxane containing at least 2 silicon-bonded hydrogen groups, (C) a platinum group metal catalyst capable of promoting the reaction between the silicon-bonded alkenyl of component (A) and the silicon-bonded reactive group of component (B), (D) a reinforcing filler (E) 0.1 to 5 percent by weight of a compound selected from the group consisting of natural dying oils and modified natural drying oils, various liquid diene compounds, and unsaturated fatty acid esters. The curable silicone coating composition is suitable for coating textiles, especially for automotive airbags. The cured coating composition has reduced tack.

Abstract: A platinum curing organosiloxane composition having improved hysteresis characteristics when cured. The composition requires the presence of a diorganovinylsiloxy terminated polydiorganosiloxane having a viscosity within a range of about 20 Pa.multidot.s to 200 Pa.multidot.s at 25.degree. C. and containing essentially no ethylenically unsaturated hydrocarbon radicals bonded to non-terminal silicon atoms and a diorganovinylsiloxy terminated polydiorganosiloxane having a viscosity within a range of about 0.1 Pa.multidot.s to 200 Pa.multidot.s at 25.degree. C., where from 1 to 5 percent of the non-terminal repeating units of the siloxane comprise a vinyl radical. In addition, the present composition comprises 10 to 30 weight percent of a reinforcing silica filler that has been treated with hexamethyldisilazane and 1,1,3,3-tetramethyl-1,3-divinyldisilazane, and an organohydrogensiloxane resin crosslinker comprising greater than 5 silicon-bonded hydrogen atoms per molecule.
