	abstract = {Synergizing coating and wood modification has the potential to achieve enhanced functionality beyond the natural ability of wood to resist dimensional instability, biodeterioration and weathering degradation. However, wood modification could impact surface thermodynamics and coatability. This study aimed at defining theoretical coatability of modified woods based on adhesion markers, namely work of adhesion, interfacial tension and spreading coefficient, derived from wetting properties and surface energetics. Eight water and solvent-based coatings with different binders that include acrylate, alkyd, natural oil and hybrid-based were explored. Acetylated, 1.3-dimethylol-4.5-dihydroxyethyleneurea-modified, furfurylated, phenol formaldehyde resin-impregnated, and sorbitol/citric acid-modified woods were investigated as substrates. A new parameter, theoretical coating delamination coefficient (CDC), was proposed as a quantitative relation between forces that support and oppose phase separation at the coating-wood interface. Practical coating-wood adhesion performance was evaluated by crosscut, scratch hardness and pull-off strength tests. Both wood modification and coating types influenced the surface energetics of wood and thermodynamic characteristics at the coating-wood interface. Based on Pearson product moment correlation, the association between CDC and actual coating-wood adhesion strength showed strong correlation for unmodified wood but mostly weak correlation for modified woods. Factoring morphological characteristics such as surface roughness could strengthen the CDC and adhesion strength correlation. Compared to traditional experimentation, this theoretical-based approach offers a more efficient method, by reducing time, material and labour inputs, in determining and/or optimizing the coatability of modified woods. This approach could potentially be applied to coatability of other substrates of different material origin or composition.},
