ABSTRACT:
Binding compositions for lignocellulosic composites comprising an aqueous emulsion containing at least one polyisocyanate and at least one water-dispersed acetovinyl resin having a glass transition temperature (Tg) lower than 5.degree. C. These compositions impart green tack cohesion to the resinate lignocellulosic material.
