Evaluation of chemical densification of three hardwood species through in-situ electron beam polymerization
2020 - IRG/WP 20-40893
Hardwoods are the most suitable species for wood flooring for their appearance as well as their hardness. Yet, improving hardness can provide substantial benefit for the wood flooring market. Chemical densification of wood and in-situ polymerization through electron beam technology was chosen to increase hardness of three hardwoods (Yellow birch (YB) (Betula alleghaniensis Britt.), Sugar maple (SM...

Unlocking the potential of tropical fast-growing hardwood species
2023 - IRG/WP 23-11010
Social forestry or community managed forestry practices have been promoted as an inclusive way to mitigate climate change through the framework of the UNFCCC scheme of the Reduce Emission Deforestation and forest Degradation (REDD+) programme. Fast growing wood species are one of the least tapped social forestry commodities in Southeast Asia, and they have the potential to be upscaled to meet the ...

A novel wood preservative with vegetal extracts-cypermethrin mixture protects H2-weathered envelope-treated tropical hardwood kempas against Coptotermes termites
2023 - IRG/WP 23-30794
In accordance with sustainability development initiatives by commercial wood protection to conceive of cost-effective, environmentally acceptable wood treatment solutions replacing traditional biocides, this paper reports an aboveground subterranean termite test of termite-susceptible heartwood blocks of the tropical (Malaysian) structural hardwood kempas (Koompassia malaccensis) envelope-treated ...

Adhesion and performance of exterior wood coatings on chemically and thermally modified wood – Results from 5.5 years outdoor exposure
2023 - IRG/WP 23-40964
Non-durable softwood and hardwood species were treated with the water-soluble cyclic N-methylol compounds 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) and methylated DMDHEU. One half of the modified specimens were coated with a waterborne acrylic coating system prior a natural weathering for 5.5 years according to EN 927-3 (2020). By frequent evaluations, the impact of chemical modifications ...

Longitudinal tensile shear properties of polyurethane-bonded preservative-impregnated Eucalyptus grandis laminates subjected to varied simulated climatic conditions
2023 - IRG/WP 23-40967
Bonding process adaptations have yielded improvements in the adhesive bonding of Eucalyptus grandis wood for manufacturing hardwood laminates. However, there are still concerns over the adhesive-bond performance, particularly preservative-impregnated E. grandis laminates, under exposure to varying climatic conditions. These concerns could limit the implementation of E. grandis laminates, especiall...
