Patent

CA 2195735

The present invention provides crosslinkable compositions comprising (A) an organosilicon compound having radicals containing aliphatic carboncarbon multiple bonds, (B) an organosilicon compound having Si-bonded hydrogen atoms, (C) a catalyst which promotes the addition of Si-bonded hydrogen onto aliphatic multiple bond, and optionally (D) an agent which retards the addition of Si-bonded hydrogen onto aliphatic multiple bond at room temperature and to the use of the crosslinkable compositions for producing coatings which repel tacky substances. The present invention also relates to organosilicon compounds having Si-bonded hydrogen atoms, and to a process for their preparation.

ompositions réticulables comprenant (A) un composé organosilicié ayant des radicaux contenant des liaisons multiples aliphatiques carbone-carbone, (B) un composé organosilicié ayant des atomes d'hydrogène liés à un Si, (C) un catalyseur qui favorise l'addition, sur une liaison multiple aliphatique, d'hydrogène lié à un Si et, facultativement, (D) un agent qui retarde l'addition, sur une liaison multiple aliphatique, d'hydrogène lié à un Si à température ambiante. En outre, l'invention a trait à l'utilisation de ces compositions réticulables pour la production de revêtements anti-adhésifs et concerne des composés organosiliciés ayant des atomes d'hydrogène liés à un Si, et à un procédé pour leur préparation.
