Wood Protection Using Nano Metal Oxides in Propylene Glycol
2022 - IRG/WP 22-30760
Metals and metal oxides are known to have properties that can protect wood from degradation. Nanoparticles, due to its unique physical and chemical properties can enhance the protection to a much greater extent. Major constraints in dealing with nanoparticle dispersion can only be resolved by identifying a proper dispersive medium. Studies were carried out by preparing nanodispersion of four metal...

Outdoor performance of Tanalith® K treated timber: Dimensional stability and corrosivity towards metal fasteners
2023 - IRG/WP 23-30798
This study was carried out to investigate dimensional stability and corrosivity towards metal fasteners in radiata pine (Pinus radiata D. Don) treated with Tanalith® K to Hazard class 4 (H4) retentions in comparison with chromated copper arsenic (CCA) treated timber. For corrosion test, untreated and treated matched specimens were prepared from Australian-grown radiata pine, tested with mild stee...

Quantifying metal migration from a deck constructed with copper-azole-treated lumber
2024 - IRG/WP 24-50391
Soluble copper or micronized copper wood preservatives are the most common available wood preservative systems for residential applications in the United States. Copper containing wood preservatives have been scrutinized for their potential negative impacts on the environment, across many jurisdictions. Concerns arise from the potential for preservatives to migrate out of treated wood upon water e...
