Abstract
Official abstract text for this publication.
The present invention aims to provide a curable composition that, while having practical curability, gives a cured product with excellent recovery, and exhibits excellent curability as well as excellent water-resistant adhesion. The curable composition includes 100 parts by weight of a reactive silyl group-containing organic polymer (A); 0.1 to 10 parts by weight of a dialkyltin disilicate compound (B); and an amino silane coupling agent (C), the dialkyltin disilicate compound (B) being a tin compound containing a bulky alkyl group and a silicate moiety with a C1 or C2 alkoxy group, and the amino silane coupling agent (C) including 1 to 10 parts by weight of an amino silane coupling agent (C1) containing a trialkoxysilyl group, and less than 1 part by weight of an amino silane coupling agent (C2) containing a dialkoxysilyl or monoalkoxysilyl group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A curable composition comprising: 100 parts by weight of an organic polymer (A) containing at least one silyl group that contains a hydroxy or hydrolyzable group bonded to a silicon atom and can form a siloxane bond to be cross-linked; 0.1 to 10 parts by weight of a silanol condensation catalyst (B); and a silane coupling agent (C) that contains a primary amino group, the silyl group in the organic polymer (A) being a group represented by formula (…
