This study investigated the effect of a plasma treatment at atmospheric pressure on the absorption characteristics of beech veneers by using a dielectric barrier discharge on the DMDHEU (1,3-dimethylol-4,5-dihydroxyethylene urea). Immersion tests with varying immersion durations showed that plasma treatment significantly accelerated the DMDHEU-solution uptake of the veneers. Additionally, improved bulking characteristics were observed for plasma-treated and DMDHEU-immersed veneers.
