Abstract
The present invention has its object to provide, by using a non-organotin curing catalyst, a curable composition having a practical level of curability. Furthermore, the present invention has its object to provide a curable composition excellent in adhesiveness while it secures a practical level of curability. The present invention relates to a curable composition which comprises: (A) an organic polymer containing a silicon-containing group capable of crosslinking by siloxane bond formation and (B) a silanol condensation catalyst: and that the silanol condensation catalyst is an amine compound and that an aqueous solution prepared by adding 5 millimoles of the amine compound to 100 g of a mixed solvent composed of isopropyl alcohol and water in a weight ratio of 10:3 has a pH value of not lower than 13.4 as measured at 23° C. according to JIS Z 8802.
