Abstract

Environmental concern accelerated development of new wood preservatives having low mammalian toxicity in addition to high protective effectiveness. PHN 130 and PHN 130 G have been developed recently by KOHMIX Ltd. in Japan as “environmentally safe”, fire-proof boron containing compounds. Beyond their proved fire-proof properties, stability of loaded chemical in wood at humid service conditions and decay resistance are required to be known for effective and broad use of these compounds in wood preservation. Results indicated that PHN imparted complete decay resistance to wood against brown- and white-rot fungi Tyromyces palustris and Coriolus versicolor, respectively. Protection efficacy of PHN also continued despite severe weathering conditions provided that impregnation is done by an undiluted solution. PHN 130 G appeared more effective than PHN 130 in this respect. However, both compounds were leachable from treated wood regardless of retention level or physical restriction of water access into wood by compression.
