CURABLE COMPOSITION

摘要

Disclosed is a curable composition using an amidine compound as a non-organic tin catalyst, which is good in elongation, flexibility, surface curability, deep-section curability and adhesion. Specifically disclosed is a curable composition containing (A) an organic polymer having a silicon-containing group represented by the following general formula (1): -SiR<SUP>1</SUP>X<SUB>2</SUB>, which polymer can be crosslinked by forming a siloxane bond, (B) an amidine compound (B-1) as a silanol condensation catalyst, and (C) a carboxylic acid. In this curable composition, the ratio between the total mole number (b) of nitrogen atoms in the component (B-1) and the total mole number (c) of carboxyl groups in the component (C) ((b)/(c)) is higher than 2.
