Weathering characteristics of impregnated and coated Calabrian pine wood

This study was designed to investigate the weathering characteristics of Calabrian pine (Pinus brutia) wood. The wood specimens were impregnated with some copper-based chemicals and then varnish coated. As chemicals, Celcure C4, Korasit KS, Tanalith E 8000 used for impregnation. Polyurethane (PV) water-based (WBV) as coating materials. Firstly, 2,5 % 5 aqueous solutions coated PV WBV. Impregnated subjected 6 months natural in Muğla, Turkey. After weathering, surface hardness, roughness, adhesion strength changes determined. Impregnation caused increase hardness values pine. Surface increases WBV higher than that specimens. resulted roughness gave all treatment groups decreased after weathering. In general, decreases concentration levels did not have a significant effect on
