ONE-PACK TYPE MOISTURE-CURING URETHANE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a one-pack type moisture-curing polyurethane resin composition having excellent storage stability and curability and suppressed foaming in curing in spite of high molar ratio of isocyanate group to hydroxy group in the urethane prepolymer. SOLUTION: The one-pack type moisture-curing urethane resin composition is produced by reacting a urethane prepolymer with an oxazolidine compound containing primary hydroxy group and adding a silyl phosphate as a curing accelerator to the obtained urethane prepolymer containing terminal isocyanate group and oxazolidine ring.
