  • Organo-acid phosphate treated pigments
    Publication number: 20040048951
    Abstract: A unique treatment for pigments is provided. This treatment, which uses certain organo-acid phosphate molecules, imparts improved physical and chemical qualities including lacing resistance, improved dispersion and decreased chemical reactivity when these treated pigments are incorporated into polymeric matrices.
    Type: Application
    Filed: August 13, 2003
    Publication date: March 11, 2004
    Applicant: Millennium Inorganic Chemicals, Inc.
    Inventors: Modasser El-Shoubary, Robert J. Kostelnik
  • Pigments treated with organosulfonic compounds
    Patent number: 6646037
    Abstract: A treatment for pigments is provided. This treatment, which uses certain organosulfonic compounds, imparts improved physical and chemical qualities including lacing resistance, improved dispersion and decreased chemical reactivity when these treated pigments are incorporated into polymeric matrices. The addition of organosulfonic compounds may flexibly be incorporated into known processes at varying points, and are preferably added downstream of any filtering steps.
    Type: Grant

  • Rheological additive comprising derivatives of castor oil
    Patent number: 5340390
    Abstract: A theological additive especially for liquid organic systems containing a castor-oil derivative with hydroxyl values below that appearing in nature. The additive may also contain clays and other extenders. The preferred derivative is castor wax. The additive largely eliminates the long term problem of seeding exhibited by paints and coatings using castor-oil derived additives while simultaneously providing improved dispersability and viscosity modifying qualities.
