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.
