Adhesive organopolysiloxane composition.

摘要

An organopolysiloxane-based adhesive composition which exhibits very reliable adhesive bonding by being cured not only at an elevated temperature but also at room temperature comprises, in addition to an alkenyl group-containing diorganopolysiloxane, an organohydrogenpolysiloxane, which serves as a crosslinking agent of the alkenyl group-containing diorganopolysiloxane by the hydrosilation reaction, and a platinum compound to catalytically promote the reaction, a compound having an alpha -substituted or unsubstituted beta -aminopropionyl group and an alkoxysilyl-substituted alkyl group such as the compounds of the formulae (CH3 O)3 Si-(CH2 ) 3-NH-(CH2 )2-CO-O-(CH2 )3-Si (OCH3 )3 ; C6 H5-CH2-NH-(CH2 )2-CO-O-(CH2 )3-Si (OCH3 )3 ; CH2 =CH-CH2-NH-(CH2 )2-CO-O-(CH2 )3-Si (OCH3 )3; and (CH3 O)3 Si-(CH2 )3-NH-(CH2 )2-CO-O-CH2 -CH=CH2.
