Evaluation of commercially available polyepoxy and polyamine to develop alternatives for wood preservation treatments

Evaluation of commercially available Beckopox polyepoxy EP 2350 and polyamine EH 613W resins to develop other alternatives for wood preservation treatments has been examined. A simple method by vacuum impregnation of these resins in different concentrations into beech and pine woods followed by a curing process at different temperatures has been conducted. Parameter analyses, such as weight gains, anti-swelling efficiency, wettability, Brinell hardness, decay durability against white-rot and brown-rot fungi and scanning electron microscopy analysis, have been evaluated. The results revealed that resin-treated wood especially cured at 103°C and 200°C presented better resistance to the leaching process, slightly better dimensional stability, lower wettability, better hardness, and very good resistance against Trametes versicolor, Poria placenta, Gloeophyllum trabeum after the leaching process.
