    摘要: 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.

    摘要: The invention relates to an aqueous fluoropolymer hybrid composition having superior weathering resistance while maintaining excellent mechanical properties in coatings, paints, caulks and adhesives. The composition is comprised of: a) a vinylidene fluoride polymer, such as KYNAR® polymers from Arkema, b) a first vinyl polymer immiscible with the vinylidene fluoride polymer and having a Tg of less than 0° C., and c) a second vinyl polymer of a different composition, also having a Tg of less than 0° C., and containing groups capable of crosslinking. The invention also relates to waterborne coatings or paints containing the aqueous fluoropolymer hybrid composition, and an article, object, or structure coated with the fluoropolymer hybrid composition on at least one surface, either in a factory or in the field, to confer protection and decorative properties. Free films made from the waterborne compositions of the invention have a dynamic mechanical analysis loss tangent, tan (δ), of greater than 0.22 at a temperature of 0° C.
