  • Apparatus for blending and dispensing foamable, curable organosiloxane compositions
    Patent number: 5330724
    Abstract: An apparatus for preparing foams exhibiting a uniformly small cell size, a minimum number of ruptured cell walls and a smooth surface from foamable curable compositions comprises means to transport the ingredients of a foamable, curable composition to the input of a static mixer in which the ingredients of the composition are blended to homogeneity prior to being extruded into an exit zone and through an exit orifice. The length to diameter ratio of the mixing zone and the diameter of the exit orifice are within specified ranges.
    Type: Grant
    Filed: April 21, 1993
    Date of Patent: July 19, 1994
    Assignee: Dow Corning Corporation
    Inventors: Therese M. Bauman, Todd S. Klenk

  • Foam mixer-applicator with foaming chamber and method of using
    Patent number: 5127552
    Abstract: A foam mixer-applicator for mixing a two-part foamable composition includes a mixing head having a mixing chamber for impingement mixing of the two component parts of the foamable composition, which are supplied to the mixing chamber in a pre-pressurized state. The mixing head is sealingly connected to a dispensing head having a foaming chamber of a substantially greater capacity than the mixing chamber and an outlet port for discharging the foam composition after foaming and acquiring a higher, yet flowable viscosity. A pneumatic plunger system pushes the foamed composition through an outlet port of the dispensing housing onto a substrate.
