<P>PROBLEM TO BE SOLVED: To provide a curable composition containing an isocyanate group-containing urethane prepolymer and an organosilicon compound which is hydrolyzed by moisture to allow regeneration of an active hydrogen-containing compound, wherein the curable composition is extremely excellent in performance of preventing foaming in a cured product even under severe conditions such as hot environments. <P>SOLUTION: There is provided a curable composition containing an isocyanate group-containing urethane prepolymer (A) and an organosilicon compound (B) which is hydrolyzed by moisture to allow regeneration of a second active hydrogen-containing compound (b-2). The concentration of an organic isocyanate compound (C) having a low molecular weight present in the curable composition is suppressed to 1 mass% or less of the entire curable composition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
