摘要
Disclosed is a liquid, solvent free, moisture curable polyurethane adhesive composition comprising the reaction products of at least one polyoxypropylene polyol having a hydroxyl functionality of at least three and ethylene oxide end-capping with one or more polyisocyanates having a weight average isocyanate functionality of greater than 2.3. The adhesive composition has a long open time and rapid cure time compared to currently available adhesives. The polyoxypropylene polyol preferably has a number average molecular weight of from 3,000 to 8,000. The composition finds special use in panel lamination applications.
