Wood Protection Through Diffusion: Dimensional Stabilisation with Amine Oxides

IRG/WP 19-30747

S Pepin, P Blanchet, V Landry

Wood is a phenomenal construction material. In addition to its great physical properties and its beautiful appearance, it possesses many environmental-friendly virtues like the sequestration of carbon dioxide. It is however subject to dimension changes when submitted to fluctuating moistures levels, which can lead to warps, cracks and the peeling of paints. Many water repellents can slow down the absorption of liquid water, but very few wood treatments have an actual effect on the absorption of air moisture (Wang & Piao, 2010). These treatments usually impregnate wood under high pressures and/or vacuum and increase significantly the density of the treated wood (Reinprecht, 2016). In this project, wood was impregnated through diffusion with amine oxides and organic fungicides. The treated wood evaluated for its dimensional stability and its uptake of chemicals.
