Abstract: The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.
