  • Specific process for preparing silicon compounds bearing fluoroalkyl groups by hydrosilylation
    Patent number: 7598409
    Abstract: The present invention relates to a process for preparing silicon compounds bearing fluoroalkyl groups by hydrosilylation of a fluoroolefin in the presence of a hydrosilylation catalyst, which comprises initially charging and heating a hydrogenchlorosilane, then metering in the fluoroolefin and reacting the reaction mixture and subsequently isolating the hydrosilylation product.
    Type: Grant
    Filed: October 21, 2004
    Date of Patent: October 6, 2009
    Assignee: Degussa AG
    Inventors: Eckhard Just, Sabine Giessler, Peter Jenkner
  • Two-component coating system for equipping smooth surfaces with easy-to-clean properties
    Patent number: 7578877
    Abstract: The present invention relates to a two-component system for equipping surfaces with an oil, water, and dirt repellent coating, the two-component system being composed of a formulation 1 and a formulation 2, and both formulations being mixed together shortly before application. The invention further relates to a method of applying the two-component system to surfaces. The invention additionally relates to the use of the two-component system.

  • Process for the hydrosilylation of unsaturated aliphatic compounds
    Patent number: 6858746
    Abstract: A compound having at least one H—Si group is reacted with an unsaturated aliphatic compound in the presence of a platinum catalyst and at least one organic additive component. The combination of platinum catalyst and additive component is one of: (i) a solution of a Pt(0) complex catalyst in a solvent, with at least one organic amide, or (ii) a solution of a Pt(0) complex catalyst in a solvent, with at least one organic amine, or (iii) a solution of a Pt(0) complex catalyst, in a solvent, with at least one organic nitrite.
