CURABLE COMPOSITION AND SEALING MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a curable composition that prevents stain components from adhering even if a sealing material is exposed to the outside for a long period of time and that excellently prevents cracks and discoloration from occurring on a surface of the sealing material, and to provide the sealing material using the same.

SOLUTION: The curable composition comprises a polysulfide polymer-containing prepolymer obtained by reacting a polyisocyanate compound (D) with a mixture of: a polysulfide polymer (A) having hydroxy group at its terminal; polyoxyalkylene polyol (B); and a hydroxy group-containing (meth)acrylic monomer (C).
