Abstract
A wood preservative composition and a method of manufacturing a wood preservative composition that includes a copper containing biocide, a zinc containing biocide, a boron containing biocide, and an azole are provided. The wood preservative composition exhibits improved biocidal efficacy against copper tolerant fungi.
Claims24
A wood preservative composition comprising:
- (a) a copper containing biocide;
- (b) a zinc containing biocide;
- (c) a boron containing biocide comprising boric acid, disodium tetraborate pentahydrate, disodium octoborate tetrahydrate, or combinations thereof;
- and
- (d) an azole,
- wherein the copper containing biocide and the zinc containing biocide are present in the wood preservative composition such that a ratio of copper ions to zinc ions is from about 15:1 to about 1:5;
- and
- wherein the copper containing biocide and the boron containing biocide are present in the wood preservative composition such that a ratio of copper ions to boric acid equivalents is from about 15:1 to about 1:5.

A method for manufacturing a wood preservative composition, the method comprising:
- (a) dispersing at least a portion of a copper containing biocide and a zinc containing biocide;
- (b) micronizing at least one azole to produce a micronized azole;
- and
- (c) combining a boron containing biocide comprising boric acid with the copper containing biocide, the zinc containing biocide, and the micronized azole;
- wherein the copper containing biocide and the zinc containing biocide are present in the wood preservative composition such that a ratio of copper ions to zinc ions is from about 15:1 to about 1:5, and
- wherein the copper containing biocide and the boron containing biocide are present in the wood preservative composition such that a ratio of copper ions to boric acid equivalents is from about 15:1 to about 1:5.
