ABSTRACT:
[Problem] There is provided a curable composition having good curability and adhesion by use of a non-organotin catalyst.[Means to Solve] A curable composition comprising (A) an organic polymer having a silicon-containing group being capable of crosslinking by forming siloxane bonds, (B) one or more kinds selected from a titanium catalyst, an aluminum catalyst and a zirconium catalyst and (C) a low molecular weight compound containing a hydrolyzable silicon group and having a molecular weight of from 100 to 1,000, characterized in that a ratio (a/b) of the total mole (a) of titanium atoms, aluminum atoms and zirconium atoms of the component (B) in the composition to the total mole (b) of silicon atoms of the component (C) in the composition is more than 0.4.
