ABSTRACT:
In a one-step process for preparing fiberboard, an aqueous treating composition comprising about 3-20%, preferably 5-15%, by weight of an acrylic or vinyl acetate emulsion or solution polymer and about 0.05 to 3.0% by weight of a fluid, water-soluble organosilicone copolymer of dimethylpolysiloxane-polyalkylene ether is applied to the fiber panel prior to final compression. The treating composition acts both as a platen release agent during compression and a tempering agent for imparting water-resistance.
