ONE-PACKAGE URETHANE ADHESIVE COMPOSITION FOR NORBORNENE RESIN, ELASTIC ADHESIVE FOR NORBORNENE RESIN AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a one-package urethane adhesive composition for norbornene resins, having excellent adhesiveness to a molded article of a norbornene resin and bondable immediately after the molding of the molded article.

SOLUTION: The one-package urethane adhesive composition for norbornene resins contains (A) a urethane prepolymer produced by reacting diphenylmethane diisocyanate with a polyol compound and (B) a urethane prepolymer produced by reacting a polyol compound with a compound containing an isocyanate group and having low reactivity with active hydrogen compared with diphenylmethane diisocyanate.
