ABSTRACT:
Complexes of sulfited tannin extract and a copper(II) ion effectively protect wood against fungal attack. The complex can be impregnated into wood in a single step treatment using a water/organic solvent system, or formed in situ by treating the wood with an aqueous solution containing the extract and subsequently treating the wood with an aqueous solution containing a copper (II) salt.
