Abstract
A prepress sealer for use in the process of making wood composition board is provided. The prepress sealer incorporates a crosslinking resin and an aqueous dispersion of acrylic polymer particles. The acrylic polymer particles have a THF gel content of greater than about 70%. Use of the prepress sealer provides improved press release during board manufacture and improved surface toughness and water resistance to the produced board.
