Abstract: Organosols of organopolysiloxanes are prepared by adding water-soluble organic solvents or mixtures thereof or water-soluble mixtures of water-soluble and water-insoluble organic solvents to aqueous, colloidal suspensions of organopolysiloxanes obtained by adding at least one alkoxysilane and/or the partial hydrolyzate thereof, and, if appropriate, mixed with an organo(poly)siloxane free of alkoxy groups and having a maximum of 8 siloxane units per molecule, to water in the presence of emulsifiers at a maximum rate of 5 moles of organosilicon compound per hour and per liter of water, and subsequently removing the water by distillation.

Abstract: Aqueous dispersions of organopolysiloxanes containing the following components:(A) Organopolysiloxane having groups which can undergo condensation;(B) condensation catalyst;(C) organopolysiloxane resin; and(D) diorganosilanolate and/or condensation products thereof formed by splitting off water.

Abstract: Structures of inorganic fibers which may contain inorganic particles, flakes or powders, are prepared by adding aqueous silicone resin emulsions containing curing catalysts and emulsifiers to the fiber material, shaping the treated fiber material, and subsequently curing the silicone resin, in which salts or chelates of trivalent iron are employed as the curing catalysts. Iron (III) acetylacetonate is preferably employed as the curing catalyst. The structures are preferably produced in a continuous process in which the aqueous silicone resin emulsion is sprayed onto the fiber material, then the fiber material is compacted to the desired bulk density and the silicone resin is cured by contacting the compacted fiber material with hot gases. Curing of the silicone resin is preferably carried out at a temperature of from 150.degree. to 300.degree. C. over a period of from 5 to 8 minutes.

Abstract: Silicone resin powders are obtained by spray drying aqueous colloidal suspensions of organopolysiloxanes which are prepared by adding an alkoxysilane and/or a partial hydrolysate thereof and, if appropriate, mixed with an organo(poly)siloxane which is free of alkoxy groups and contains a maximum of 8 siloxane units per molecule, to water in the presence of an emulsifier at a maximum rate of 5 moles of organosilicon compound per hour per liter of water.

Abstract: Colloidal suspensions of organopolysiloxanes are prepared by mixing an organosilicon compound selected from the group consisting of mixtures of alkoxysilanes and/or partial hydrolysates thereof and an organo(poly)siloxane which is optionally free of alkoxy groups and contains a maximum of 8 siloxane units, which is mixed with at least one alkoxysilane and/or a partial hydrolysate thereof, with water in the presence of an emulsifier, at a maximum rate of 5 moles of organosilicon compound per hour per liter of water, in which the organosilicon compound and the water is fed continuously, but separately from one another, into a reactor, in which at least one of the two substances contains an emulsifier, while the alkanol is being continuously removed by distillation from the aqueous suspension continuously emerging from the reactor. The aqueous suspension from which the alkanol has been removed by distillation is, if desired, recycled back into the reactor.
