The Paint and Coatings industry uses accelerated testing to extrapolate performance in real world situations and ensure coating formulations will withstand the forces of nature and provide longterm durability. This paper will compare the performance data of the three most common accelerated exposure test methods: QUV-A (ASTM D 4587), Xenon Arc (ASTM D 6695), and EMMAQUA (ASTM D 4141) and correlate this data to the same systems exposed for 10 years in South Florida and in North Kansas City, Missouri. We will show the importance of formulation design and the critical impact that ingredients have on the long-term performance of the coating. This study will compare high performance polyurethane, polysiloxane, and fluoropolymer technologies. We will also demonstrate that the combination of accelerated test methods can be used to predict long-term performance in different longitudinal zones which have varying degrees of solar radiation.
