Copper naphthenate-protecting America's infrastructure for over 100 years and its potential for expanded use in Canada and Europe

This paper reviews the history and use of copper naphthenate as a heavy-duty wood preservative, with a focus on use patterns within the USA and opportunities for expansion in Canada and Europe. Copper naphthenate has demonstrated efficacy to preserve and protect cellulosic and wooden items essential to critical infrastructure and is an ideal choice for use in the replacement of pentachlorophenol and creosote where less toxic and environmentally friendlier alternatives are required.
