water-borne preservative
An inorganic, water-soluble compound, as ammoniacal copper arsenite (ACA) or chromated copper arsenite (CCA), used as a wood preservative. ACA and CCA affix chemically to the wood cell walls and is resistant to leaching. The copper acts as a fungicide while the arsenate is toxic to wood-destroying insects. Wood treated with ACA and CCA is odorless and paintable. (Ching, 1995)
