  • Fluororesin coating composition for forming a topcoat and coating film therefrom
    Patent number: 11970628
    Abstract: Provided is a fluororesin coating composition for forming a topcoat having improved non-tackiness and water and oil repellency. The fluororesin is crystalline tetrafluoroethylene and perfluoro(ethyl vinyl ether) copolymer having a perfluoro(ethyl vinyl ether) content of 8 to 20 mass % based on the total mass of the copolymer.
    Type: Grant
    Filed: July 24, 2017
    Date of Patent: April 30, 2024
    Assignees: THE CHEMOURS COMPANY FC, LLC, CHEMOURS-MITSUI FLUOROPRODUCTS CO., LTD.
    Inventors: Daisaku Shinohara, Kazuhiko Miyagishima
  • Fluoropolymer coating composition
    Patent number: 11926754
    Abstract: Provided is a coating film having excellent durability and wear resistance, and utility as mold surface release coating. The coating film has excellent releasability (non-adhesiveness) over a long period of time. Further provided is a coating composition capable of forming such a coating film, the coating composition containing a fluoropolymer and an oil that is a liquid at 25° C., wherein the decomposition temperature of the oil is higher than the melting point of the fluoropolymer.
