LONG-CHAIN ALPHA-ACETYLEN ALCOHOL AS HYDROSILYLATION INHIBITORS, AND THEIR APPLICATION FOR THE PREPARATION OF STABLE, HARDENABLE SILICONS COMPOSITIONS

摘要

The present invention relates to an alpha-acetylenic long chain alcohol as a reaction of hydrosilylation inhibitor, its use, its application for the preparation of stable curable silicone compositions, its component and its method for obtaining nonadherent items. The acetylenic alcohol reaction hydrosilylation inhibitor, has the formula: R- (R ') C (OH) -C ~ CH (I) wherein R is a linear or branched alkyl, or a phenyl radical, R' is H or R, R, R 'radicals and the atom atoms located in .alpha. the triple bond optionally to form a ring, the total number of carbon atoms contained in R and R 'being at least 9. The alcohol of the invention is used as hydrosilylation inhibitor in curable compositions basis of a silicone-based functions alkenyl oil and / or an adhesion modifier to SiAlcényle functions resin, optionally an adhesion modifier resin SiH functions, a silicone crosslinking agent SiH functional groups and a hydrosilylation catalyst.
