  • Publication number: 20210206990
    Abstract: The present invention addresses the problem of providing powder paint compositions and liquid paint compositions for baking, which have excellent corrosion resistance and workability as well as high durability and chemical resistance, and form a good lining film free from failures such as cracks; and a coating film and coated objects comprising such powder paint compositions or liquid paint compositions for baking. Powder paint compositions for baking comprise fluororesin where one or more types of porous coordination polymer (PCP)/metal-organic framework (MOF) formed by coordinate bonds between organic ligands and central metals disperse.

  • Patent number: 10435581
    Abstract: Provided are a chromium-free fluoropolymer-containing primer composition, which can provide a coated article having excellent higher corrosion resistance by forming a fluoropolymer coating film, and a primer layer having sufficient adhesive strength to the fluoropolymer coating film on the surface of a substrate such as metal, glass, ceramic and heat resistant plastics, a method for manufacturing a coating film using the same, and a coated article using the same. The coating composition contains at least one kind of a fluoropolymer component selected from a reactive functional group-containing fluoropolymer, and a fluoropolymer having a melt flow rate (MFR), measured under a load of 5 kg and at 372° C., in accordance with ASTM D1238, of 10 to 100 g/10 minutes, and an organic titanate, wherein content of titanium contained in the organic titanate, relative to the fluoropolymer component, is 1 to 40% by weight.
