  • Coating of metal pigments using phosphonic acid-based compounds
    Patent number: 9139715
    Abstract: A coated metal pigment that has excellent passivation, dispersion and adhesion properties, a method for producing the coated metal pigment and a coating composition that includes the coated metal pigment are described.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: September 22, 2015
    Assignee: Silberline Manufacturing Co., Inc.
    Inventors: Anand Sundararaman, Yungwan Kwak, Craig Keemer, John Buchala, Mary Kate Thomas, Chang Xu, Parfait Jean Marie Likibi
  • Colored system
    Patent number: 8815982
    Abstract: A colored system including a coated substrate and a color pigment that adheres to the coated substrate, and a method for producing the colored system are described. The disclosed method adheres effectively the color pigments to the coated substrates. The resulting colored system avoids their separation during coating applications. The colored metallic paints/inks can be prepared by mixing a color pigment solution with a coated substrate solution. The resulting colored system displays vivid color and strong metallic luster.

  • Microwave susceptor for cooking and browning applications
    Publication number: 20060213906
    Abstract: A microwaveable food container includes an even mixture of metal particles and insulating particles. The mixture of metal and insulating particles allows higher heat to be generated at the surface and applied more evenly to the food, resulting in better browning of certain foods and better cooking of dough-based products such as pizza. Methods of making food containers, methods of cooking, and compositions useful for making food containers also are disclosed.
