MOISTURE-CURING POLYURETHANE HOT MELT COMPOSITION CURABLE WITH MOISTURE

摘要

PROBLEM TO BE SOLVED: To provide a moisture-curing polyurethane hot melt composition which can form a cured product very excellent in flexibility and bending properties at low temperature. SOLUTION: The moisture-curing polyurethane hot melt composition contains a urethane prepolymer prepared by reacting a polyol (A) with a polyisocyanate (B). The polyol (A) includes a polyester polyol (a-1) prepared by condensation reaction of a polyether polyol in which an alkylene oxide is added to bisphenol A with a polycarboxylic acid and a polytetramethyleneoxy glycol (a-2).
