Patent ID: 11401419

Abstract:
This dealcoholization room-temperature curable organopolysiloxane composition contains (A) a diorganopolysiloxane having a silicon atom-bonded hydroxy group and/or a hydrolyzable silyl group at both ends of the molecular chain, and has a coefficient of viscosity of 20-1,000,000 mPa·s, (B) an organopolysiloxane which is a partial (co-)hydrolysis-condensation product of a hydrolyzable organosilane compound having one or more silicon atom-bonded alkenyl groups and 1-3 silicon atom-bonded alkoxy groups, per molecule, (C) a hydrolyzable organosilane compound having one or more phenylene backbones and two or more amino groups, per molecule, and/or a partial hydrolysis-condensation product thereof. The dealcoholization room-temperature curable organopolysiloxane composition has good curability and storage stability even when the composition does not contain a metal catalyst, is less toxic to the human body and is environmentally friendly, is cost-competitive, and has good rubber physical properties and adhesiveness after being cured.
