  • Continuous process for producing crosslinkable organopolysiloxane compositions
    Patent number: 7888421
    Abstract: RTV-1 compositions are continuously produced from essentially linear organosilicon compounds having at least two condensable groups bound to silicon, filler and, optionally, further constituents, by mixing in one step in a single pass through the mixing zone of a rotor-stator mixer, wherein the pressure at the outlet of the mixing apparatus is at least 100 hPa greater than that at the inlet of the mixing apparatus.
    Type: Grant
    Filed: July 25, 2007
    Date of Patent: February 15, 2011
    Assignee: Wacker Chemie AG
    Inventors: Peter Schöley, Uwe Scheim, Steffen Lau
