In the production of non-adherent coated paper substrate by applying to the substrate a solvent-containing mixture comprising (A) an .alpha.,.omega.-polyorganosiloxanediol, (B) an organosiloxane containing Si-H groups, (C) an alkyl- or alkenyl-triacetoxysiloxane, (D) an organic isocyanate with more than two isocyanate radicals and (E) a hardening catalyst, and then heating the substrate to harden the coating, the improvement which comprises including in the mixture applied to the substrate a reaction product (F) of a chloromethylpolymethylsiloxane of the formula

Production of non-stick coatings

A process for the production of polymeric organosiloxanes comprising reacting diorganosiloxanes with substances regulating the chain length in the presence of alkaline and/or acid reaction catalysts and wherein the polymerization takes place in a reactor consisting of several zones and is provided with stirring or conveying elements, the arrangement of the stirring or conveying elements being such that the flow of material produced by the stirring or conveying element in each zone is the opposite of that in the adjacent zone or zones.

Process for the continuous preparation of polydiorganosiloxanes

In the preparation of cyclic and linear organosiloxanes by reacting an organohalogenosilane with a compound of the formula

Preparation of organosiloxanes

A process for the preparation of an organopolysiloxanol comprising contacting at least one organochlorosilane of the formula
