  • Patent number: 7803867
    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.

  • Publication number: 20100233461
    Abstract: The invention relates to a colored, multi-layered composition having a high level of Total Solar Reflectance (TSR). The composition includes a thin top, weatherable layer having a minimal amount of colored pigment suitable for optical hiding. In one embodiment a pigmented topcoat having less than 12 percent colored (non-white) pigment in a KYNAR AQUATEC emulsion (Arkema Inc.) is placed over a white elastomeric acrylic primer on a substrate to produce a colored multiplayer composition with a TSR of greater than 70%.

  • Patent number: 7399533
    Abstract: The invention relates to a one-step fluoropolymer, especially polyvinylidene fluoride (PVDF), coating for use on metals, especially use on metal fuel line and brake tubes, etc, to provide a protective barrier with superior chemical resistance, impact resistance and heat resistance as well as good flexibility. The coating composition contains, on a resin solids basis, 75-94 percent polyvinylidene fluoride resin, 5-20 percent acrylic resin, and 1-15 percent polyepoxide resin. The coating has excellent adhesion on metal substrates, particularly on non-pretreated galvanized steel, without the need for a primer coating.

  • Patent number: 7037966
    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.

  • Patent number: 6833414
    Abstract: A cross-linkable fluoropolymer dispersion is described and involves a polymer product of at least one polymerizable acrylic and/or vinyl containing monomer and at least one hydrolytically stable silane containing monomer which are in the presence of an aqueous dispersion of at least one fluoropolymer. The present invention further relates to cross-linkable fluoropolymer blends wherein at least one polymer contains acrylic units, vinyl units, or both and at least one hydrolytically stable silane or silane containing group in the presence of at least one thermoplastic fluoropolymer. The silane or silane containing group can alternatively be present in the thermoplastic fluoropolymer. Methods of making the cross-linkable fluoropolymers are also described as well as products containing the cross-linkable fluoropolymer dispersions such as paints and coatings.
