  • Method for preparing self releasing silicone foams and method of reducing cycle time of producing silicone foams
    Patent number: 5614567
    Abstract: A method of preparing a self-releasing silicone foam in which a composition containing a siloxane polymer, an organohydrogensiloxane, a platinum catalyst, a polyol, and preferably a monofunctional alcohol is foamed, cured, and then post cured at an elevated temperature. A method of reducing the cycle time of preparing a cured silicone foam in which the above composition is applied to a plastic substrate, foamed, cured, post cured at an elevated temperature and then separated from the plastic substrate.
    Type: Grant

    Date of Patent: March 25, 1997
    Assignee: Dow Corning Corporation

  • Curable silicone compositions which are foams or elastomers
    Patent number: 5574073
    Abstract: What is disclosed herein relates to curable silicone compositions which provide high strength foams or elastomers. These foams or elastomers have high strength properties which are provided by a combination of non-resinous organopolysiloxanes as the base polymer. The high strength properties are better than the high strength properties of cured silicone compositions where only one non-resinous organopolysiloxane polymer type is employed. These compositions have the added benefit of being less expensive than resin based formulations.

  • Flow aid
    Patent number: 4208388
    Abstract: The flowability of particulate lime is enhanced by treatment with effective amounts of selected fluid polymethylhydrogensiloxanes, polydimethylsiloxanes, and/or mixtures thereof.
