Title:
TWO-COMPONENT TYPE ROOM TEMPERATURE RAPID-CURABLE RESIN COMPOSITION AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2024/014350
Kind Code:
A1
Abstract:
This two-component type room temperature rapid-curable resin composition comprises, at a specific ratio: a first agent containing, at a specific ratio, (A) an organic polymer in which the molecule chain terminals are blocked by a hydrolysable silyl group and/or a hydroxyl silyl group, and in which an organopolysiloxane structure is not included in the polymer main chain, (B) a hydrolyzable organosilane compound represented by formula (1) (in formula (1), R1 represents a monovalent hydrocarbon group, n represents 1-8, and m represents 3 or 4) and/or a partial hydrolysis condensate thereof, and (C) a curing catalyst; and a second agent containing (A') an organic polymer in which the molecule chain terminals are blocked by a hydrolysable silyl group and/or a hydroxyl silyl group, and in which an organopolysiloxane structure is not included in the polymer main chain. The two-component type room temperature rapid-curable resin composition has excellent rapid curability and deep curability, provides fine workability, and, when being cured, causes elimination/release of a cyclic ketone compound such as cyclobutanone and cyclopentanone as a leaving group (elimination compound). Thus, the composition solves problems regarding safety and hazardous properties with respect to human and the environment.
