Copper Chromated Arsenic
Chromated copper arsenic (CCA), is a waterborne wood preservative introduced into wood by pressure impregnation. The active ingredients are chromium (47.5%), arsenic (34.0%) and copper (18.5%). The extraordinary effectiveness of CCA as a wood preservative lies in the combined action of these three elements. Copper, acts as a fungicide; arsenate, a form of arsenic, is an insecticide; and chromium, binds the ingredients to the wood.
