Abstract
A method is disclosed for preparing compression molded or pressed lignocellulosic articles. The method involves forming a binder resin by combining a polyisocyanate component with a synergist component of a C1 to C4 N-alkyl pyrrolidone, gamma-butyrolactone, or mixtures thereof. A resinated lignocellulosic mixture is formed by combining the binder resin with lignocellulosic particles having a moisture content of from 2 to 15 weight percent. The compression molded or pressed lignocellulosic article is formed by compressing the resinated lignocellulosic mixture.
