Abstract
A wood preservative composition resulting from admixing components comprising: at least one preservative metal; a quaternary ammonium compound; at least 2 amine compounds; a pH reducing agent, and water, wherein the pH of the composition is from about 7.1 to less than 8.5. Surprisingly, this combination of materials results in a stable solution that can contain a moldicide yet have a commercially acceptable shelf life.
