It was requested that exposure testing be completed on various high durability coatings products to evaluate gloss retention and color changes. Various systems were chosen to test, some with clear coats and some without. They were placed in cyclic UV/condensation testing, concentrated natural sunlight testing in Arizona, and outdoor exposure testing in South Florida. The coating systems that exhibited the best results were those that included a fluoropolymer coating. Rank order correlations among the various sites showed that results were very similar, with concentrated natural sunlight testing and outdoor exposure in Florida having the best correlations for gloss and color retention results. Calculated acceleration factors for this study were 1:2 for concentrated natural sunlight testing versus cyclic UV/condensation, 1:7 between concentrated sunlight and Florida outdoor exposure, and 1:5 between cyclic UV/condensation and Florida.
