A water comprising, two component polyurethane dispersion adhesive comprising an anionic polyester polyurethane resin and a solvent-free liquid aliphatic polyisocyanate cross-linker. The dispersion can be reactivated one or more times for edge bonding a flexible sheet material onto a substrate having a main surface, a peripheral surface and an edge connecting the main surface and the peripheral surface. Un adhesivo de dispersión de poliuretano que comprende agua de dos componentes comprende una resina de poliéster-poliuretano aniónica y un agente reticulante de poliisocianato alifático líquido libre de disolventes. La dispersión puede ser reactivada una o más veces para la pegadura de bordes de un material de hoja flexible sobre un sustrato que tiene una superficie principal, una superficie periférica y un borde que conecta la superficie principal y la superficie periférica.
