  • Coating of poly(arylene sulfide), fluoropolymer and aluminum flake
    Patent number: 4287112
    Abstract: A coating composition of poly(arylene sulfide), fluoropolymer and aluminum flake, in a liquid carrier which is either aqueous or organic, provides durable coatings especially useful in bakeware.
    Type: Grant
    Filed: January 10, 1980
    Date of Patent: September 1, 1981
    Assignee: E. I. Du Pont de Nemours and Company
    Inventor: Jacques M. L. Berghmans
  • Substrate with multi-layer nonstick coating
    Patent number: 4223069
    Abstract: A three-coat system for use on bakeware which has a silvery appearance and can be cured at low temperatures. First, an epoxide-formaldehyde-nitrogen resin primer, which may contain aluminum flake, is applied to the substrate, then a reactive silicone-epoxy coat containing talc and coarse aluminum flake is applied. Finally, a less reactive silicone resin containing coarse aluminum flake, but no other pigment is applied. The two final coats are applied directly on the preceding coat after only ambient temperature air drying. After the final coat is applied, the coated article is baked at temperatures that need not exceed 275.degree. C.
