TITLE OF THE INVENTION: METHOD FOR BONDING LIGNOCELLULOSIC MATERIAL WITH GASEOUS ESTERS ABSTRACT OF THE DISCLOSURE: A method for bonding lignocellulosic material under heat and pressure together with steam and a gaseous ester is disclosed. According to the method, a mat of lignocellulosic material with a curable aqueous alkali solution of a phenol-formaldehyde resole binder is compressed between a pair of heated press platens to a first intermediate density and thickness, and condensable steam is injected into the mat through openings in said platens; the mat is then further compressed to a final density and thickness; and an ester in gaseous form is injected into said mat to cure a portion of the binder. Following the gaseous ester injection, the mat may be further injected with high pressure steam to cause further cure or elimination of uncured formaldehyde. A vacuum or exhaust is optionally applied to the mat through the platen opening to remove excess steam and other vapor, and the press is opened to remove the board formed from the mat.
