Wood preservatives, widely used in the wood industry, pose a risk to human health and the environment due to their harmful chemical structure. Due to the awareness of society and environmental pressures, it is searching for natural preservatives compatible with the ecological environment. Resins, which do not contain any hardening and toxic chemicals in their components, have been preferred as surface treatment materials since ancient times due to their water-repellent properties and compatibility with wood materials. This study aimed to determine the adhesion effect of resin-based lacquer used in lacquering food packaging materials, which does not contain hardeners and harmful solvents, as a surface protector on wood materials. The study preferred three local wood species and resin lacquer (food lacquer) as surface treatment materials. In this context, samples prepared from Oriental beech (Fagus Orientalis Lipsky), Scots pine (Pinus Sylvestris L.), and Anatolian chestnut (Castanea sativa Mill.) according to ISO 3129 principles were acclimatized by TS ISO 13061-1 principles and resin lacquer was applied to the surface of the test samples by spraying method according to ASTM-D 3023 principles. After the surface treatment, the samples were cured (hardener) in an oven (fan-drying oven) at temperatures of 60, 80, and 100 °C. The samples coated with resin lacquer were measured for adhesion according to TS EN ISO 4624. The test data were subjected to statistical analysis in the MSTAT-C program. According to the results, the analysis of variance regarding the effects of wood species and temperature on the adhesion value was found to be statistically significant (α=0.05) regarding wood species and temperature changes but insignificant in terms of their interactions. In the interaction of wood species and oven temperature, the highest surface adhesion value was obtained at Oriental beech + 100 °C (2,821 N/mm²) and the lowest at Scots pine + 60 °C (2,00 N/mm²).
