Abstract
The present invention has its object to provide a curable composition which comprises a reactive silyl group-containing organic polymer, does not contain, as a silanol condensation catalyst, any organotin type curing catalyst currently of concern because of the toxic feature thereof, is excellent in surface curability and depth curability and, further, can provide cured products excellent in adhesiveness; the above object can be achieved by a curable composition which comprises: an organic polymer (A) containing a silicon-containing group capable of crosslinking under siloxane bond formation; and a guanidine compound (B-1), as a silanol condensation catalyst (B), represented by the general formula (1):R1N═C(NR12)2 (1)(wherein one of the five R1s is an aryl group and the other four R1s each independently is a hydrogen atom or a hydrocarbon group in which the carbon atom at position 1 is saturated).
