Title:
ROOM TEMPERATURE CURABLE ORGANOPOLYSILOXANE COMPOSITION, ARTICLE, HYDROLYZABLE ORGANOSILANE COMPOUND AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/113437
Kind Code:
A1
Abstract:
The present invention provides: a room temperature curable organopolysiloxane composition which has curability equivalent to the curability of conventional dealcoholization type or deoximation type room temperature curable organopolysiloxane compositions even if various catalysts are used therefor, while reducing harmful effects on human bodies and burden on the environment, and which enables the achievement of a cured product that has good rubber properties, adhesiveness and durability if cured; various articles which comprise this composition or a cured product that is obtained by curing this composition; a novel hydrolyzable organosilane compound which is useful as a curing agent for this composition; and a method for producing this novel hydrolyzable organosilane compound. A room temperature curable organopolysiloxane composition which contains, as a curing agent, a hydrolyzable organosilane compound that is represented by general formula (2) and releases/discharges a cyclic ketone compound as a leaving group and/or a partial hydrolysis-condensation product of the hydrolyzable organosilane compound. (In the formula, R2 represents a monovalent hydrocarbon group having from 1 to 10 carbon atoms; n represents a number from 1 to 8; and m represents 3 or 4.)
