title: Reducing leaching of boron-based wood preservatives - a review of research.
abstract: Inorganic borates offer good protection to timber in most non-ground contact applications. The effective use of low solubility borates has not yet been achieved in the treatment of solid lumber. Interest in reducing the leaching of borates stems from their favorable environmental characteristics and broad spectrum efficacy. The key to extending the use of borates to cover the entire spectrum of wood preservation is improving their permanence in wood while retaining efficacy by retaining limited mobility of the borate. We review research over the last two decades in laboratories around the world and classify all strategies employed into fifteen categories. For each strategy, resistance of the treated wood to wood destroying organisms, resistance to leaching, and potential applications are discussed.
