Abstract
Preservative compositions for wood products is 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.

A preservative composition for a wood product comprising:
- boric anhydride;
- methyltrichlorosilane;
- and
- at least one solvent.
A preservative composition comprising:
- boric anhydride;
- methyltrichlorosilane;
- at least one solvent;
- and
- wherein the methyltrichlorosilane is present in the at least one solvent at a concentration of 1 to 3 volume percent.
A method for protecting a wood product, said method comprising the steps of:
- providing a composition comprising at least one material containing silane and at least one hydrocarbon solvent;
- contacting the wood product with the composition and penetrating and diffusing the silane into the wood product;
- and
- wherein the at least one material containing silane is present in the hydrocarbon solvent at a concentration of 1 to 3 volume percent.
