Document Type and Number:
WIPO Patent Application WO/2023/068094
Kind Code:
A1
Abstract:
Provided is a room temperature-curable (RTV) silicone rubber composition which exhibits excellent rapid curing properties and adhesive properties without adding an environmentally harmful metal-based condensation catalyst which was commonly used in the past, exhibits good storage stability, and can yield a cured product that exhibits durability (heat resistance and moisture resistance). This room temperature-curable organopolysiloxane composition contains: (A) an organopolysiloxane; (B) a hydrolyzable organosilane compound having two hydrolyzable silyl-vinylene groups on the same silicon atom; (C) an inorganic filler; and (D) an amino-functional group-containing hydrolyzable organosilane compound having three or more nitrogen atoms in one molecule and/or a partial hydrolytic condensation product thereof.
