PROBLEM TO BE SOLVED: To improve storage stability of a liquid curable composition while giving it thixotropy, despite of its viscosity remaining low.SOLUTION: The curable composition includes an organic polymer (A) having a crosslinkable silicon group and whose main chain is not polysiloxane, a filler (B), and an organic solvent (C) having a boiling point of not greater than 150°C. The filler is surface-treated colloidal calcium carbonate treated with a fatty acid ester as a surface-treating agent. The organic solvent is contained by 10 pts.wt or more with respect to 100 pts.wt of the organic polymer. Preferably, the organic polymer is at least one selected from the group consisting of a polyoxyalkylene polymer, (meth)acrylic acid ester polymer, and a saturated hydrocarbon polymer. More preferably, the organic polymer is a mixture of a polyoxyalkylene polymer and a (meth)acrylic acid ester polymer. The fatty acid ester is, preferably, a saturated fatty acid ester having carbon atoms of not less than 3 and not greater than 100. |
