STORAGE-STABLE ORGANOPOLYSILOXANE COMPOSITIONS WHICH CAN BE CROSSLINKED TO GIVE ELASTOMERS WITH ELIMINATION OF ALCOHOLS

摘要

Stable RTV-1-alkoxy compositions contain a tin catalyst and surfactants (S) which contain divalent polyether units of the general formul a (I) -O-[(CR.alpha.R.beta.)u-O]v- (I) in which R.alpha. and R.beta. are hydrogen or a monovalent C1-C10 hydrocarbon radical optionally substituted by hydroxyl, fluorine, chlorine, bromine, C1-C10 alkoxyalkyl or cyano groups, u is from 1 to 6 and v is from 3 to 100. The compositions are stable despite the presence of the tin catalyst and alkoxy-functional organosilicon compounds.
