Surface Adhesion Strength of Varnishes in Some Impregnated Woods

M. Atar and M.H. Colakoglu

Abstract:
This study was performed to determine the impact of impregnation chemicals on the surface adhesion strength of varnishes in some woods. For this purpose, Scotch pine, Oriental spruce and Uludağ fir woods were used according to ASTM 358. Test samples were impregnated with boric acid (Ba) and borax (Bx) by vacuum technique according to ASTM D 1413. After impregnation process cellulosic (Cv), synthetic (Sn), polyurethane (Pu), waterborne (Wb), acrylic (Ac) and acid hardening (Ah) varnishes were applied on the surface of test samples according to ASTM D 3023. Adhesion strength test was conducted on the test specimens after varnishing process was determined according to ASTM D 4541. According to the test results, the highest adhesion strength was obtained in Scotch pine impregnated with borax and varnished with acrylic varnish, and the lowest was obtained in Uludağ fir impregnated with boric acid and varnished with cellulosic varnish. As a consequence, Scotch pine+Borax+Acrylic varnish combination is recommended for usage in usage areas having a high risk of varnish abrasion resistance.
