An object of the present invention is to provide a curable composition which has good curability and good tensile properties (high elongation), and contains a smaller amount of a dibutyltin compound which is regarded as toxic. The curable composition of the present invention comprises the following components (A) and (B) at a weight ratio of (A)/(B) of 25/75 to 75/25, (A) a reactive silyl group-containing organic polymer having, as a silicon-containing group cross-linkable by siloxane bond formation, a group represented by the formula (1): -SiX 3 , and (B) a reactive silyl group-containing organic polymer having, as a silicon-containing group cross-linkable by siloxane bond formation, a moiety represented by the formula (2):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-O-R l -CH(CH 3 )-CH 2 -Si(R 2 3-a )X a
- wherein a is 1 or 2. |
