ABSTRACT:
Preservative compositions for wood products are described. The compositions include at least one boron-containing material, such as but not limited to boric anhydride, and at least one silane-containing material, such as but not limited to methyltrichlorosilane. Optionally, at least one solvent, such as tetrahydrofuran, pentane, or water, may also be employed in the compositions. The compositions impart protection to the treated wood products, especially damage caused by exposure to water and insects.
