Kúdela, Jozef, 1954- Influence of accelerated ageing on colour and gloss changes in tree of heaven surface treated with an iruxil coating system / Jozef Kúdela, Martina Štrbová, František Jaš. -- Obr., tab. -- Lit. - This work investigates the influence of accelerated ageing on surface-treated wood. The assessment was carried out through evaluation of changes in visual properties (colour, gloss) in wood surface treated with water-based coating system applied in different colour hues. The system was adjusted by the manufacturer, to be used for wood surface modification guaranteeing resistance during outdoor exposure. The coating system was applied on veneers prepared of tree of heaven (Ailanthus altissima). The results obtained for the studied properties demonstrate that the coating system had a high resistance against photo-degradation. Under the dry mode (UV radiation without rainfall simulation), no obvious changes to the coating occured. Under the wet mode (UV radiation with rainfall simulation), some colour changes were present, and the coating got darker and more matt. These changes, however, were not immediately observable visually. The coating systems containing darker pigments showed more colour stability than the ligher hues. The better covering capacity of darker pigments as well as the bigger amounts of these pigments in the coatings resulted in better protection of the wood surface against UV-induced degradation.
