CURABLE COMPOSITION WITH IMPROVED CURABILITY AND ADHESIVENESS

摘要

[PROBLEMS] Disclosed is a curable composition which exhibits good curability and good adhesiveness while using a catalyst other than organic tin catalysts. [MEANS FOR SOLVING PROBLEMS] Specifically disclosed is a curable composition containing an organic polymer (A) containing a reactive silicon group as a silicon-containing group which can be crosslinked by forming a siloxane bond, one or more catalysts (B) selected from titanium catalysts, aluminum catalysts and zirconium catalysts, and a low molecular weight compound (C) with a molecular weight of 100-1000 containing a hydrolyzable silicon group, which curable composition is characterized in that the ratio (a/b) between the total mole number (a) of titanium atoms, aluminum atoms and zirconium atoms in the component (B) and the total mole number (b) of silicon atoms in the component (C) is larger than 0.08.
