The present invention relates to the preparation of organooxychlorosilanes. They are produced by reacting the corresponding chlorosilane with an alcohol in the presence of a catalyst system consisting of hydrogen chloride and a cocatalyst.

Process for the preparation of organooxychlorosilanes

A silicone composition which is stable in the absence of moisture but which in the presence of water will cure at room temperature to an elastomer, comprising a polyorganosiloxane having reactive end groups, a polyester and a thickening filler.

Polyorganosiloxane compositions which harden into elastomers at room

In a polydiorganosilixane composition which is capable of storage in the absence of moisture and can be cured at ambient temperature under the action of water or moisture to give elastomers, the composition comprising a diorganosiloxane having reactive terminal groups, a diorganosilane having groups which are sensitive to hydrolysis, a cross-linking agent, and optionally fillers which have a thixotropic effect, condensation catalysts and/or other known auxiliaries, the improvement which comprises employing as the silane (a) a silane of the formula

RTV Silicone pastes

A silicone emulsion which can be converted into an elastomeric product under ambient conditions by eliminating and evaporating water and alcohol or carboxylic acid, comprising by weight approximately
