An isocyanate bonded wood composite, such as a doorskin, comprising about 95% to about 99% by weight wood fiber, about 1% to about 4% by weight of an organic isocyanate and 0% to about 2% by weight of a wax, and its method of manufacture, are disclosed. The isocyanate bonded wood composite is manufactured by admixing the ingredients, then pressing the admixed ingredients at a temperature of about 200 DEG F. to about 320 DEG F., for a sufficient time and at a sufficient pressure, to provide an isocyanate bonded wood composite having a density of about 0.9 g/cc to about 1.1 g/cc, and that demonstrates improved porosity and adhesive properties. |
