In this work, a set of solvent-borne coatings for wood protection and finishing, 7 industrial and 2 experimental, was studied to verify their performance and the effects of artificial weathering. The aim of this work was to evaluate the coatings’ properties in terms of their hydrophobic properties, protection against UV, preservation of wood colour and formation of checks on the surface of samples. The wood used in this research was aspen (Populus tremula), which was thermally treated under the following conditions: 160°C for 3 h, and 170°C for 1 h, and also untreated specimens were used. Specimens were coated with 2 or 3 layers of coating, but for all of them the external layer was the same. Coatings were applied avoiding the formation of a visible film on the wood surface. Colour, surface integrity, and wettability were monitored before, during and after the weathering.
Keywords: wood surface, coatings, artificial weathering, colour, wettability
