Evaluation of Commercially Available Polyurethane Resin to Develop Non-biocidal Wood Preservation Treatments
2016 - IRG/WP 16-40751
Evaluation of commercially available polyurethane (PU1 and PU2 and polyisocyanate (PNCO) to develop non-biocidal wood preservation treatments have been conducted. A simple method by vacuum impregnation of these resins into beech wood (Fagus sylvatica L) and pine wood (Pinus sylvestris L.) samples followed by varied curing process at ambient temperature, 103oC, and 200oC have been performed. Based ...

Development of beech wood thermo-chemical modification treatments based on different vinylic derivatives of glycerol and polyglycerol
2019 - IRG/WP 19-40855
In this study, a combination between chemical and thermal wood modification has been investigated. Seven types of a low concentration of 10% aqueous additive solution of vinylicglycerol [glycerol-maleic anhydride (Gly-MA), glycidyl methacrylate (GM), and Glycerol methacrylate-maleic anhydride (GM/MA(2eq))], vinylicpolyglycerol [polyglycerol-maleic anhydride (PG-MA), polyglycerol methacrylate (PGM...

Promoting Commercially Available Epoxy Resins for Non-biocidal Wood Preservation
2019 - IRG/WP 19-40877
Commercially available epoxy and polyamine resins were evaluated with the aim of developing new non-biocidal wood preservation treatments. A simple method allowing the impregnation of wood by vacuum double impregnation followed by a curing process was developed for two reference species, beech Fagus sylvatica and Scots pine Pinus sylvestris. The tested products were evaluated for their ability to ...

Mechanical and biological durability properties against soft-rot and subterranean termite in the field (grave-yard test) of beech wood impregnated with different derivatives of glycerol or polyglycerol and maleic anhydride followed by thermal modification in an opened or in a closed system
2021 - IRG/WP 21-40917
This paper presents mechanical and biological durability properties in soil beg test (soft-rot test) and field test (grave-yard test) against subterranean termite of the wood modified with an aqueous vinylic derivative of glycerol/polyglycerol or maleic anhydride cured in an opened or in a closed system. Wood modification was performed through impregnation of European beech (Fagus sylvatica) with ...

The effect of sapwood and heartwood differences on durability of short rotation teak wood
2022 - IRG/WP 22-10991
Short rotation teak has been developed to overcome the limited supply of long rotation teak. The aim of this study was to investigate the effect of sapwood and heartwood differences on durability of short rotation teak. The following basic properties were studied: extractive content, dimensional stability (volumetric swelling and water uptake), decay resistance, and termite resistance. The result...

Environmentally Friendly Wood Modification based on Tannin-Furfuryl alcohol - Effect on stabilisation, mechanical properties and decay durability
2022 - IRG/WP 22-40929
Furfurylation is a well-known wood modification technology. This paper studied the effect of tannin addition on the wood furfurylation. Three kinds of dicarboxylic acids, adipic acid, succinic acid, and tartaric acid, as well as glyoxal as a comparing agent, were used to catalyse the polymerisation of furanic or tannin-furanic solutions during wood modification. Impregnation of furanic or tannin-f...

Improvement of durability of Scots pine against termites by impregnation with citric acid and glycerol followed by in situ polyesterification
2023 - IRG/WP 23-30777
Scots pine (Pinus sylvestris) sapwood samples were impregnated with solution containing citric acid (CA) and glycerol (Gly) followed by heating 140 °C according to already described procedure (L'hostis et al. 2018). The resulting modified woods were then used to evaluate the effect of chemical modification on the durability against termites. Two kinds of experiments were conducted for this purpos...
