摘要
A study was performed exposing seven automotive OEM coatings (base coat/clear coat paint systems) outdoors in Jacksonville and to different variants of the acid dew and fog (ADF) test, a new approach to simulating the worst case of the weather conditions in harsh urban and industrial environments. Varying the climatic conditions and the severity of the simulated acid precipitation, a certain variant of the ADF test was found to show a satisfying practice correlation. Profilometric and chemical analysis revealed that the coatings differ in the rate of photodegradation after an acid attack due to the penetration of acid solution. (C) 2000 Elsevier Science S.A.
