  • Opacifying particles with internal void and methods for making the same
    Patent number: 9388288
    Abstract: The invention includes a method of preparing an aqueous dispersion of particles at least partially encapsulated by a polymer, the method comprising dispersing inorganic particles in an aqueous phase; functionalizing at least a portion of the surfaces of the inorganic particles with a coupling agent, the coupling agent having pendent reactive groups; polymerizing the reactive groups on the functionalized particles with a first polymerizable component to produce inner polymer shells surrounding the inorganic particles; polymerizing a second polymerizable component to form outer polymer shells at least partially encapsulating the inner polymer shells; and producing voids within the outer polymer shells, such that the inorganic particles are received within the voids.
    Type: Grant
    Filed: March 4, 2013
    Date of Patent: July 12, 2016
    Assignee: PPG Industries Ohio, Inc.
    Inventors: Noel Vanier, Xiangling Xu, Wei Wang, Shanti Swarup, Michael Pawlik, David Asay
  • METHOD OF RECOVERING INORGANIC PIGMENT
    Publication number: 20140275348
    Abstract: Disclosed is a method of recovering inorganic pigment such as TiO2 from a coating composition that includes liquid, an organic component, and an inorganic component. The coating composition is thermally treated to remove at least a portion of the organic component and yield an inorganic pigment composition having a higher concentration of the inorganic pigment (TiO2) than in the original coating composition.

  • RUBBER FORMULATIONS INCLUDING GRAPHENIC CARBON PARTICLES
    Publication number: 20130296479
    Abstract: Rubber formulations comprising a base rubber composition, graphenic carbon particles, and non-conductive filler particles such as silica are disclosed. The formulations possess favorable properties such as relatively low surface resistivities, and are useful for many applications such as tire treads.
