PROBLEM TO BE SOLVED: To provide a curable composition which can withstand sufficiently long working time and is useful as sealing materials for construction, coatings and adhesives. SOLUTION: A curable composition comprising a polymer (a) having two or more active hydrogen atoms in its molecule, a curing agent of a polyisocyanate compound (b) having two or more isocyanate groups in its molecule and zeolite (c), wherein the zeolite (c) is preferably a natural zeolite, and is preferably compounded in a mixing proportion of 1-50 pts.wt. relative to 100 pts.wt. of the polymer (a) having two or more active hydrogen atoms in its molecule.
