Abstract
The invention relates to an aqueous-based fluoropolymer coating that is especially useful for use over flat or low-slope flexible surfaces, and more specifically for flat or low-slope roofing. The coating can be factory or field applied. The coating offers the advantages of improved durability, lower dirt pick-up, stain resistance, water repellency, increased solar reflectivity duration, and mildew resistance.
