Abstract
A method of manufacturing a finished product from a lignocellulosic material selected from the group consisting of lignocellulosic particles or fibers, soft boards, and board precursors in sheet form includes the steps of impregnating the lignocellulosic material with an impregnating composition consisting of a mineral oil and a liquid thermosetting resin, optionally with a catalyst therefor. Thereafter, the lignocellulosic material is compressed with heating to allow the mineral oil to infuse the lignocellulosic material and to polymerize the thermosetting resin to form the finished product.
