PROBLEM TO BE SOLVED: To provide a curable composition that is excellent in workability due to long usable time and rapid curability, and whose cured product shows low specific gravity while maintaining good tensile behavior.SOLUTION: A curable composition comprises: (a) a polymer that contains two or more thiol groups in one molecule; (b) a compound that contains two or more isocyanate groups in one molecule; (c) a tertiary amine; (d) at least one compound chosen from an organic titanium compound, an organic zirconium compound, an organic aluminum compound, and an organic tin compound; and (e) a microballoon. |
