Copper Naphthenate – A Data and Capability Update

IRG/WP 22-30771

J-W Kim, J D Lloyd

The efficacy of copper naphthenate against wood decay fungi and wood destroying organisms has been well documented from international field tests as well as decades of commercial service. The use of copper naphthenate has been dramatically expanded due to its proven performance, non-restricted use, minimal environmental impact, and superior end of life options. Extensive demand and interest has also been driven by the future loss of pentachlorophenol in North America and of Creosote in Europe. This paper is a brief update on these developments including some examples taken from field and laboratory tests showing the impact of different formulations and carrier oils. The operational capabilities implemented to keep up with this increased demand have also been highlighted.
