Building materials based on polyisocyanate-impregnated lignocellulosic substrates provide increased strength and water, fire, insect, and fungi resistance compared to prior art building materials. At the same time, such building materials exhibit an aesthetically pleasing surface and can, therefore, be used in consumer visible applications (such as furniture) as well as in consumer invisible (such as door frames and stiles) applications.

Resin impregnated substrate materials

The disclosed invention relates to polyisocyanate-impregnated lignocellulosic substrates having improved strength, water resistance and appearance, and also to methods and systems for producing such substrates. The polyisocyanate-impregnated lignocellulosic substrate are produced by impregnating a lignocellulosic substrate with an isocyanate resin, followed by polymerization of the isocyanate resin by applying a heated liquid to the impregnated substrate.
