PlasmaSolution – Curing of coating formulations using non-thermal plasmas
2020 - IRG/WP 20-40904
Coatings are an important part of wood protection, especially for outdoor applications. In order to provide a good protection, protective coatings need to exhibit good adhesion, mechanical resistance, and weathering resistance. Plasma pre-treatments are an established method to increase the performance of existing coatings including those on wood and wood-based substrates. Moreover, plasma deposit...

Discrimination of five commercial wood preservatives by handheld near-infrared spectrometers and Multivariate Data Analysis
2022 - IRG/WP 22-20686
Nowadays, the recycling potential of wood waste is still limited, because of a lack of reliable lack of a reliable and fast device allowing the discrimination of preservative-treated wood that contains organic or/and inorganic contaminants. The purpose of this study was to set up a methodology, based on a SCiO low-cost handheld NIR spectrometer, and multivariate data analysis (MDA). Spectra was ob...

Brief introduction to a research project on preparations of various paste formulations from boron, fluoride and copper for supplemental treatments
2022 - IRG/WP 22-30759
Wood preservatives to be used for supplemental purposes are present in various forms such as powders, liquids, rods, pastes, or gels. Boron compounds have been receiving a lot of attention in supplemental treatments since they have good mobility in wood. Application of boron compounds via internal treatments is vital to stop decay to be occurred inside the wood since large wood elements are too th...

Susceptibility of selected Australian commercial timbers to West Indian drywood termite Cryptotermes brevis
2023 - IRG/WP 23-11003
West Indian drywood termite (Cryptotermes brevis) is a globally distributed timber pest and is invasive in Queensland, Australia, causing widespread damage to structures and large economic impacts in control and repair costs. Despite this, the knowledge of which specific timbers are susceptible to attack is limited and requires investigation. Two six-week feeding trials were performed, exposing se...

Potential of plant polyphenol extracts in pesticide formulations against Xylophagous insects
2023 - IRG/WP 23-30790
Termite castes (soldiers, nymphs, and reproductives) are unable to feed themselves and are fed via trophallaxis from the workers which degrade the cellulose from wood. It is of great economical importance to ascertain the efficacy of preservatives against wood decay organisms in order to extend wood products service life. Remedial chemical product applications are used primarily as wood treatments...

Evaluation of the efficacy of silver nanoparticles and chitosan oligomer composites as poplar wood protective treatments against termites
2023 - IRG/WP 23-40963
Populus × euramericana ‘I-214’ (poplar) is a fast-growing species widely distributed throughout the world, and in the Castile-Leon region of Spain it accounts for more than 50% of all plantations. Its wood is becoming increasingly appreciated, yet its low durability against xylophagous agents —termites being one of the most aggressive and destructive in warm climates— continues to be a li...

Evaluation of mass timber materials for military and commercial trailer decking
2024 - IRG/WP 24-41009
In this study, CLT trailer decking was manufactured to current military trailer decking specifications, verified using PRG320 performance criteria, and treated with either waterborne or oil borne wood preservatives. Preliminary results show adequate uptake of preservative solution and subsequent testing shows minimal effect due to treatment. Field durability tests are also being conducted of treat...
