(57) [Summary] [Object] The present invention improves the storage stability of a curable composition containing at least one reactive silicon group in a molecule and containing a saturated hydrocarbon polymer as a main component. The purpose is to do. [Structure] (A) a saturated hydrocarbon polymer having at least one reactive silicon group in the molecule and having a molecular weight of 500 to 30,000; and (B) a general formula (1) RC (OR ' ) 3 (1) (in the formula, R is a hydrogen atom or a substituted or unsubstituted hydrocarbon group, R'is a substituted or unsubstituted hydrocarbon group, and three R's are the same or different) A curable composition having improved storage stability, which comprises an ortho organic acid ester. |
