Abstract
The invention provides improved release agents used in processes for preparing molded lignocellulosic articles. The release agents are preferably applied as an emulsion in processes for preparing molded articles such as oriented strand 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.degree. C. and the second wax has a Brookfield viscosity which is less than about 100 mPas at 140.degree. C.
