ABSTRACT This study was performed to determine the effects of varnishing after impregnation with boron compounds on the combustion properties of Scotch pine. For this purpose, test samples prepared from Scotch pine ( Pinus sylvestris Lipsky ) wood were impregnated according to ASTM-D 1413-99 standard with boric acid (Ba) and borax (Bx) by vacuum technique. After impregnation, surfaces were coated by cellulosic (Cv), synthetic (Sn), polyurathane (Pu), waterborne (Wb), acrylic (Ac) and acid hardening (Ah) varnishes in accordance with ASTM D-3023 standard and then, combustion temperature was determined. According to material and process type, combustion temperature was...
