Abstract

The study investigated the effects of short-term thermo-mechanical (STTM) densification temperature and pressure on changes in surface wettability of veneer of different wood species (alder, beech, birch and pine). Veneer sheets were densified using pressure levels of 4, 8 and 12 MPa at three temperatures: 100, 150 and 200 °C for a short time of 4 min. The wettability analysis showed that in a relatively short process time wettability can be changed significantly; STTM-densified veneer surfaces became more hydrophobic.
