Abstract
The present invention has its object to provide a curable composition not containing any organotin type curing catalyst of concern because of the toxic feature thereof, or any volatile compound, excellent in curability and storage stability and, further, capable of providing cured products excellent in strength and elongation. The above object can be achieved by a curable composition which includes: an organic polymer (A) containing a hydrolyzable silyl group in a molecule; an amidine compound (B); a plasticizer (C); and an amino group-containing silane coupling agent (D), wherein the amidine compound (B) is preliminarily mixed and dissolved and/or dispersed in the plasticizer (C) and the amino group-containing silane coupling agent (D), and the resultant mixture is added to the reactive silyl group-containing polymer (A).
