PROBLEM TO BE SOLVED: To provide a reactive hot-melt adhesive composition preventing bulging by carbon dioxide generated in a curing process of a moisture-curable type reactive hot-melt adhesive, suitable for adherend having wide area, particularly door panel, desk top board, etc. and excellent in adhesiveness and appearance. SOLUTION: The reactive hot-melt adhesive composition is obtained by formulating 100 pts.wt. isocyanate-ended polyurethane prepolymer obtained by reacting a (1) a polyol containing 5-35 wt.% polyester polyol containing a diol or a dicarboxylic acid having≥8C alkylene group as a unit and having≥3,000 molecular weight with (2) a polyisocyanate with (3) 0.3-5 pts.wt. zeolite powder. The average particle diameter of the zeolite powder is preferably 10-100μm. COPYRIGHT: (C)2008,JPO&INPIT
