Abstract

The article provides information on the change in color distance and a reliable forecast model for this process during natural exposure of paint coating systems for 7 years in a moderately warm climate. It is revealed that the seasonality effect, previously detected based on data for 1 year of exposure, decreases after 3,5 years and is not observed after 5 years of exposure. It is proven that it is possible to reliably forecast changes in color characteristics for up to 7 years after analyzing experimental data for 5 years of natural exposure.
