Abstract
A preservative for wood and other organic materials subject to biological deterioration. The preservative contains an amine-forming biologically active metal; polyphosphate, amine, chlorinated phenols and carbon dioxide. The mole ratios between polyphosphate and amine-forming metal is 0.5 - 1.5, between amine and amine-forming metal 1 - 7; between amine and carbon dioxide 1 - 4 and between amine-forming metal and chlorinated phenole, calculated as pentachlorophenol 0.5 - 15.
