The effect of nano-wollastonite on moisture resistance in sealer-killer and sealersemi-polyester paints on Fagus orientalis, Abies sp. and Populus sp

In furniture production, polishing processes are very important for the technical, economic, and aesthetic performance of wood materials. Thus, surface coating with paints can protect wood against specific environmental factors such as moisture, changes in dimensions, and degradation by microorganisms including fungi. This study aimed to investigate the effect of nano-wollastonite (0, 5, and 10%) on moisture resistance in sealer-killer and sealer-semi-polyester paints on Fagus orientalis, Abies sp, and Populus sp. The results showed that among the studied species, beech treated with nano and without nano had better adhesion resistance compared with Abies. Also, the performance of semi-polyester paint was better on tensile strength compared with killer paint. Finally, the highest adhesion resistance was related to the 5% nano-wollastonite.
