Abstract
The present disclosure includes a wood composite made from cellulosic particles, a binder, and a water-repelling agent. In some embodiments, the water repelling agent includes aliphatic compounds having a molecular distribution between about 16 and about 36 carbon atoms per molecule. In some embodiments, the water-repelling agent has an average molecular weight of about 220 to about 350 Daltons (solids portion). The water-repelling agent may be applied as a wax emulsion or in neat wax form. The present disclosure also relates to a method for manufacturing a wood composite as described above.
