The NatureWood® ACQ® preservative is a waterborne, Alkaline Copper Quaternary preservative system developed to provide long-term protection to wood exposed in exterior applications. The ACQ NatureWood system is based on Copper combined with a quaternary ammonium compound and is applied to wood by pressure treatment. Copper and quaternary ammonium compounds are effective fungicides and termiticides. Together they provide protection against a broad spectrum of decay fungi, borer and termites.
