Abstract
The invention relates to a fluoropolymer resin-based composition useful as a stain resistant coating. The coating composition contains organosilicates and at least one water-scavenger, and has an extended pot life. Articles coated with the composition show superior weatherability, dirt shedding, and stain resistance, without a negative effect on gloss. The coating is especially useful on roofing materials, wall materials and other outdoor building materials.
