PROBLEM TO BE SOLVED: To provide a curable composition giving a cured product with good weatherability, particularly excellent surface weatherability, and suitable for a sealing material for construction. SOLUTION: This curable composition comprises mainly a reactive silicon group-containing oxyalkylene polymer (A) with≥4,000 Mn and having a urethane bond, and a triazine-based UV absorber (B) as an inevitable ingredient. A hindered phenol-based antioxidant may be used together with the triazine-based UV absorber (B). COPYRIGHT: (C)2008,JPO&INPIT
