Abstract: ABSTRACT:The impact of impregnation and bleaching on the hardness of varnish layers on oak (Quercus petraea L.) wood was investigated. A number of solutions [sodium hydroxide (NaOH) (natural) wood panels. Subsequently, a water-based varnish (WB) was coated over the samples, and the hardness of the varnished layers was determined in accordance with ASTM D 4366. Among the samples that were varnish-coated without bleaching, T-CBC/WB yielded the highest hardness (59.50), whereas I-WR 2000/WB exhibited the lowes… Show more

“…In a similar research, it was reported that in the impregnation of oak the retention decreased with the increase in impregnation period. This may be due to tyloses in oak wood samples [24].…”

“…The hardness values of varnished but unimpregnated samples were lower than those of impregnated and varnished samples. The impregnation materials showed an increasing effect in the hardness values of cellulosic, synthetic, polyurethane, waterborne, acrylic, and acid hardening varnishes at rates of 15,8,6,8, and 9% in boric acid and 9, 3, 10, 11, and 14% in borax, respectively. With the acid hardening varnish, the hardness increased by 7% in boric acid but decreased by 6% in borax.…”

“…Depending on the bleaching treatment types, the average highest varnish layer hardness (swing) was measured in Tanalith‐CBC + NaSiO 3 ‐H 2 O 2 + water‐borne treated samples (62.67) whereas the lowest in Imersol‐WR 2000 + KMnO4‐NaHSO3‐ H 2 O 2 + water‐borne treated samples (43.50) in Oriental beech wood 10. Depending on the bleaching treatment types, the average highest varnish layer hardness (swing) was measured in Tanalith‐CBC + NaOH + Ca(OH) 2 + H 2 O 2 + water‐borne treated samples (56.50) whereas the lowest in Imersol‐WR 2000 + NaHSO 3 + H 2 C 2 O 4 2H 2 + water borne treated samples (40.83) in oak 11…”
