  • Organosilicon compounds
    Patent number: 7553983
    Abstract: Transesterified organosilicon compounds, including ionic organosilicon compounds and coupling agents, and aqueous-based compositions including transesterified organosilicon compounds are provided. Compositions comprising at least one transesterified organosilicon are suitable for application to various inorganic, organic and cullulosic surfaces for imparting water repellency and improved wetting. Compositions comprising transesterified organosilicon compounds exhibit reduced flammability, improved hydrolytic stability, reduced gloss and improved water repellency while maintaining reactivity with various substrates.
    Type: Grant
    Filed: July 24, 2007
    Date of Patent: June 30, 2009
    Assignee: Zydex Industries
    Inventors: Ajay Ishwarlal Ranka, Praksh Vithaldas Mehta
  • Ionic organosilicon compounds and compositions thereof
    Patent number: 7521573
    Abstract: Ionic organosilicon compounds are provided comprising ethylene glycol functionality and aqueous compositions comprising such ionic organosilicon compounds; wherein the aqueous compositions are suitable for imparting water repellency to a wide variety of surfaces. The compositions of the present invention are prepared by dissolving ionic organosilicon compounds in water. Surprisingly, it has been found that the water soluble ionic organosilicon compounds, which have an ionic group, a hydrophobic group and at least one alkoxy group on silicon, of the present invention provide treated surfaces with excellent hydrophobicity.
