The possible effect of oak extractives leaching on prolongation of the exterior transparent coating durability
Original language description
This research deals with the impact of extractives leaching from oak wood, due to weather exposure (sunlight and rain action), on prolongation of service life of the transparent coating system. Samples of oak wood (Quercus robur, L.) were exposed to the exterior conditions in Prague according to EN 927 3 for 20 weeks. The extractives of oak are rapidly photodegraded (ZAHRI ET AL 2007) and washed out due to rain, which causes color change.The results showed a significantly positive effect of using the top hydrophobic layer to increase the durability and color stability of the tested coating systems (see C versus CH in Figures 2 and 3). The top hydrophobic layers can extend the service life of the coating systems for exterior conditions (GHOSCH ET AL 2009). The work confirmed this statement for oak wood, which is a problematic timber from the view of surface treatment with transparent coating systems.
