Abstract

There is provided a curable composition having good curability and adhesion by using a non-organotin catalyst.The curable composition comprising (A) an organic polymer having a reactive silicon group as 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 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) to the total mole (b) of silicon atoms of the component (c) is larger than 0.08.
