What is CCA and How Does It Work?
The chemical used to preserve Wolmanized® Heavy Duty™ pressure-treated wood is a mixture of the oxides of copper, chromium, and arsenate known as CCA. The preservative has been formulated to render wood useless as a food substance for termites and fungi while keeping the wood attractive, clean, odorless, non-staining, and safe to handle when used as recommended.

Unlike the commercially produced trivalent arsenic, the arsenate in Wolman® CCA is in the form of inorganic pentavalent arsenate-a naturally occurring trace element. In the treatment process, the pentavalent arsenate becomes fixed, or chemically bound, in the wood cells as highly leach-resistant insoluble precipitates.
