Coating adhesion and wettability of aged and preweathered fir wood
Outdoor weathering of unprotected wood can cause severe surface degradation. This preweathering before finishing can lead to chemical and physical changes on the wood surface that can influence wood-coating interface. The change in wettability of wood surface with weathering and a change in adhesion strength of acrylic water based coating on preweathered fir wood (Abies Alba Mill.) and pine wood (Pinus silvestris L.)samples were evaluated. Wettability of fir wood and pine wood samples increased with time of weathering as shown by the decreasing contact angle. Adhesion of acrylic coating to fir wood significantly reduced after wood substrate had weathered for 2 to 6 weeks. The influence of preweathering on adhesion strength of acrylic coating on pine wood samples was not established.
