A binder for use in the preparation of a synthetic board from cellulosic and/or lignocellulosic material comprising an organic polyisocyanate and a mixture of reactive hydrogen-containing compounds having an average of more than one reactive hydrogen atom per molecule, the mixture containing an ester and/or an amide having a hydrocarbon content sufficient to bring about enhanced board release in the board-forming process and to contribute to superior moisture resistance in the finished board. |
