Abstract
Lignocellulose composite products that include a hydrophobizing agent. The lignocellulose composite product can include a plurality of lignocellulose substrates, an at least partially cured binder composition, and a hydrophobizing agent. In one example, the hydrophobizing agent can include about 30 wt % to about 98 wt % of a fatty acid compound, about 0.1 wt % to about 15 wt % of a rosin acid compound, and about 1 wt % to about 40 wt % of an unsaponifiable compound. In another example, the hydrophobizing agent can include a tall oil pitch and a fatty acid composition.
