Title:
TWO-PACK TYPE ROOM TEMPERATURE CURABLE ORGANOPOLYSILOXANE COMPOSITION AND VARIOUS ARTICLES CONTAINING SAID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/234084
Kind Code:
A1
Abstract:
The present invention provides a two-pack type room temperature curable organopolysiloxane composition which exhibits both excellent fast curing properties and excellent bonding properties without the addition of a metal-based condensation catalyst that has a high environmental load, and which is capable of providing a cured product hat has good durability (heat resistance and moisture resistance). The present invention provides a two-pack type room temperature curable organopolysiloxane composition which is composed of: a first agent that contains (A) an organopolysiloxane having both molecular chain ends blocked with organooxy groups and (B) a hydrolyzable organosilane compound having two hydrolyzable silyl-vinylene groups on the same silicon atom; and a second agent that contains (C) an organopolysiloxane having both molecular chain ends blocked with silanol groups, (D) an amino functional group-containing hydrolyzable organosilane compound having three or more nitrogen atoms in each molecule and/or a partial hydrolysis-condensation product thereof, and (E) 0.1 to 5 parts by mass of an organic compound having a ketone group.
