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.

Claims (28)

1. A preservative composition comprising:

at least one material containing silane;

at least one solvent;

wherein the at least one solvent contains at least one of pentane, heptane, hexane, or combinations thereof to penetrate and diffuse into a material contacted by the preservative composition; and

wherein the at least one material containing silane is methyltrichlorosilane.

2. A preservative composition comprising:

methyltrichiorosilane; and

pentane to penetrate and diffuse into a material contacted by the preservative composition.

3. A preservative composition comprising:

methyltrichiorosilane; and

hexane to penetrate and diffuse into a material contacted by the preservative composition.

4. A preservative composition comprising:

methyltrichiorosilane; and

heptane to penetrate and diffuse into a material contacted by the preservative composition.

5. A preservative composition comprising:

methyltrichlorosilane;

at least one hydrocarbon solvent to penetrate and diffuse into a material contacted by the preservative composition; and

wherein the at least one hydrocarbon solvent is selected from the group consisting of pentane, heptane, hexane, and combinations thereof.

6. A preservative composition comprising:

methyltrichlorosilane;

at least one hydrocarbon solvent to penetrate and diffuse into a material contacted by the preservative composition; and

wherein the methyltrichlorosilane is dissolved in a material selected from the group consisting of pentane, hexane, heptane, and combinations thereof.

7. A method for protecting a wood product comprising:

providing a composition comprising at least one material containing silane and at least one solvent containing pentane; and

contacting the wood product with the composition and penetrating and diffusing the silane into the wood product.

8. A method for protecting a wood product comprising:
