ABSTRACT OF THE DISCLOSURE Wood surfaces are bonded together by heating and pressing using a preferably dry binder formulation constituting a thorough mixture of an isocyanate and a sugar or starch, the binder formulation also preferably containing a stabilizer and optionally a catalyst and a release agent. The binder formulation may be used with good results in an amount equal to the amount of straight isocyanate resin which would normally be used, i.e. the sugar or starch replaces a quantity of the isocyanate which would normally have been used, thereby reducing the total quantity of isocyanate, thus reducing cost without any disadvantage.
