Influence of climatic conditions and surface roughness on the wettability of medium density fiberboards (MDF)

Wettability of wood surface is measured by the contact angle between the liquid and the surface of the wood. In this study, the wettability of MDF surfaces was measured using different mixtures of distilled water and isopropanol. The results reveal that TF-bonded MDF made from fresh and recycled fibers showed better wettability than the corresponding MUF-bonded MDF. Moreover, the entire results indicate that roughness is one of the most important influencing factors on the wettability of MDF surfaces.
