An aqueous two-component polyurethane dispersion adhesive comprises an anionic polyester polyurethane resin and a liquid aliphatic polyisocyanate crosslinker that is free of a solvent. The dispersion may be reactivated one or more times to bond the flexible sheet edge to a substrate having a major surface, a peripheral surface, and an edge connecting the major surface and the peripheral surface. 一种含水双组分聚氨酯分散体粘合剂，所述粘合剂包括阴离子聚酯聚氨酯树脂和不含溶剂的液体脂族多异氰酸酯交联剂。所述分散体可以再活化一次或多次以将柔性片材边缘粘合到具有主表面、外围表面以及连接主表面和外围表面的边缘的基材上。
