Critical view on the possibility of color changes prediction in the surfaces of painted wood exposed outdoors using accelerated weathering in Xenotest

Popis výsledku v původním jazyce

The capability to correlate exactly the process of outdoor natural weathering for the coating systems on wood surfaces via their artificial weathering in laboratory conditions would significantly reduce the testing times. In this work, a weathering of 16 different coating systems applied on two wood species (Norway spruce and black locust) having two different degrees of roughness (smooth, rough) was performed with the aim to compare direction and intensity of their color changes in natural exterior exposure without ground contact lasting from 6 to 36months and in Xenotest lasting from 1 to 12weeks, respectively. Correlation relationships between the natural and accelerated weathering of painted woods have been evaluated based on linear regressions for changing of the CIE-L a b color parameters L and E and by non-linear Spearman rank correlation of E values. The results exhibit better possibilities for correlating the color changes for wood painted with pigmented coatings compared to transparent one
