Evaluation of the effects of modified micronized copper azole (MCA) and chromated copper arsenate (CCA) on decay resistance and mechanical properties of selected Canadian timber species

The proposed research project aims to work alongside Canada’s largest wood preservation company, Stella-Jones, to help solve an ongoing industrial challenge. Since phasing out the popular wood preservative chromated copper arsenate (CCA) for residential use in the early 2000’s, the wood preservation industry has begun to formulate new wood preservatives as an alternative. Since these new wood preservatives are intended for residential use, their composition is primarily made to exhibit a desired colour (brown) rather than a desired decay resistance. However, the new preservatives have shown challenges including discoloration and failure to protect against wood-rot fungi. Working directly with an industry partner such as Stella-Jones, this research will help to maximize the company’s (and industry’s) production and product quality.
