Wood surface roughness, free energy (SFE), wettability, and bonding quality for water-based acrylic coatings were investigated. The samples tested in this study included Pinus radiata, sylvestris, Larch, Hemp oak, Catalpa tree, Camphor. Sandpaper with grits of 180, 240, 320, 400, 500 was utilized to sand wood surfaces. van OSS-Chaudhury-Good equation (vOCG) used calculate the SFE values. modifi...
