Wood-coating layer studies by X-ray imaging

Abstract : The penetration depth into wood structure by different wood finishes (solvent-borne, waterborne or powder) was assessed using a non-destructive analysis method, that is, X-ray tomography. The coating thickness was also evaluated. The results obtained from the image analysis by two specific softwares, namely VGStudio MAX(A (R)) and ImageJ(A (R)), are compared and discussed by taking into account the chemical properties and anatomy of wood materials and the nature of finishes. The degree of coating penetration is mainly determined by its ability to flow into capillaries, and it was observed that resin type, solid matter content and drying method influence this ability.
