RELEASE AGENTS FOR USE IN LIGNOCELLULOSIC PROCESSES AND PROCESS FOR PREPARING MOLDED LIGNOCELLULOSIC COMPOSITES

摘要

The invention provides improved release agents used in processes for prepari ng molded lignocellulosic articles. The release agents are preferably applied a s an emulsion in processes for preparing molded articles such as oriented stra nd board, waferboard or plywood. The release agents contain a co-oxidized blend of a first wax and a second wax, wherein the first wax has a Brookfield viscosity which is at least about 150 mPas at 140 ~C and the second wax has a Brookfield viscosity which is less than about 100 mPas at 140 ~C.
