  • Continuous process for polymerization and emulsification of siloxane
    Patent number: 8580862
    Abstract: A method and apparatus for making silicone-in-water emulsions comprising high viscosity silicone polymers is provided. In various aspects, polyorganosiloxanes are polymerized into high viscosity silicone polymers then emulsified in a continuous process, wherein the process is carried out using a single apparatus. In some aspects, the provided apparatus is an extruder for polymerizing polyorganosiloxanes into high viscosity silicone polymers and then emulsifying such polymers.
    Type: Grant
    Filed: April 15, 2010
    Date of Patent: November 12, 2013
    Assignee: Dow Corning Corporation
    Inventors: Kathleen Ann Barnes, David Shawn Tascarella, Dan J. Julian, Donald Taylor Liles

  • PROCESS FOR MAKING SILICONE-IN-WATER EMULSIONS
    Publication number: 20080242744
    Abstract: A process is disclosed for making a silicone-in-water emulsion by forming a hydrophobic phase containing a silicone component, mixing one or more surfactants with the hydrophobic phase, adding water to the hydrophobic phase and shear mixing in a twin-screw extruder to form a silicone in water emulsion.

  • Curable coating compositions from emulsions of elastomeric polymers and polyurethane dispersions
    Patent number: 6825263
    Abstract: A curable coating composition comprises: (A) a water continuous emulsion comprising a curable elastomeric polymer having a viscosity of 0.5-1,000,000 KPa-s and a glass transition temperature up to 50° C.; (B) an aqueous polyurethane dispersion; and optionally, (C) a cure agent. Methods for preparing the curable coating compositions are also disclosed. The curable coating composition and the cured coatings derived from the reaction product of this composition are useful as fabric coatings, and in particular for decreasing air permeability of the coated fabrics at relatively lower coating weights.
