  • Publication number: 20100160551
    Abstract: A hybrid alkyd acrylic latex and a process for its preparation are taught. The process comprises forming an oil phase comprising an alkyd, a drier, and at least one ethylenically unsaturated monomer, wherein the oil phase solubilizes the drier; combining the oil phase with an aqueous phase, wherein the aqueous phase comprises a surfactant, to form a pre-emulsion; homogenizing the pre-emulsion thereby forming a miniemulsion, wherein the drier is solubilized in the oil phase; initiating the polymerization by adding a free radical initiator, thereby polymerizing the at least one ethylenically unsaturated monomer in the miniemulsion and forming a latex polymer emulsion having latex polymer particle sizes in the range of 40 nm to 700 nm.

  • Publication number: 20070292677
    Abstract: The present invention is a coating composition comprising at least one type of bead material in a dispersion medium, wherein the dispersion medium can be an aqueous or non-aqueous-based dispersion. This invention is also directed to a coated surface comprising a two-layer coating system comprising a topcoat and an undercoat, wherein the topcoat is an aqueous or non-aqueous dispersion comprising at least one type of bead material; and wherein the undercoat is a waterborne dispersion comprising one or more highly water-absorbent pigments. This invention is also directed to a process for achieving an aesthetic appearance on a surface utilizing a beaded topcoat applied over an undercoat comprising one or more highly water-absorbent pigments.

  • Patent number: 7129278
    Abstract: The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates. According to this invention, polymer dispersions can be produced from low acid value polymers and yet have good water dispersibility. When an aqueous coating composition is formulated using the dispersion of this invention, a final coating is formed that has good hydrolytic stability, and when blended with a latex, exhibits improved gloss and wet adhesion.
