Abstract: The water-soluble, silicone-modified resin compositions comprise (a) an interpolymer with an acid value of 10 to 150 prepared by the reaction of a polyol, a polybasic carboxylic acid or an anhydride thereof and an alkoxy- or hydroxy-containing organosilicon compound, (b) a water-miscible organic solvent and (c) a basic compound in an amount sufficient to decrease the acid value of component (a) to below 5 or preferably to zero. The compositions, when diluted with water as desired, are useful as a water-soluble varnishes or a water-soluble paint vehicles capable of forming coating films with excellent weathering resistance, heat-stability, anti-corrosion, solvent resistance and other properties.

Abstract: The organopolysiloxane compositions comprising a dimethylpolysiloxane, an organohydrogenpolysiloxane, a silica filler, zinc carbonate, ceric oxide, and a platinum compound. They are useful for producing electrically insulating materials and fire-resistant materials with excellent heat stability and flame retardancy.
