  • Adhesive primer composition and bonding method employing same
    Patent number: 4534815
    Abstract: A mixture of an organosilicon compound having at least one alkoxy or alkoxyalkoxy radical per molecule, vinyltris(tertiary-butylperoxy)silane, and organic solvent is an adhesive primer composition useful for bonding thermosetting silicone rubber to a substrate, especially for bonding fluorosilicone rubber to a substrate. The adhesive primer composition can be used in a method of bonding thermosetting silicone rubber to a substrate.

  • Silicone compositions for adhesion and method for adhering silicone rubber to a substrate
    Patent number: 4332844
    Abstract: A silicone composition prepared from an alkoxy-containing silicon compound, an organotitanate, and an organohydrogensilicon compound, optionally an organic solvent is useful for improving the adhesion between silicone rubber and a substrate.
    Type: Grant
    Filed: January 2, 1981
    Date of Patent: June 1, 1982
    Assignee: Toray Silicone Limited
    Inventors: Mitsuo Hamada, Sadami Yasuda, Chiichiro Hasegawa
  • Flame retardant silicone rubber compositions
    Patent number: 4310444
    Abstract: Flame retardant silicone rubber can be prepared from organopolysiloxane, silica filler, platinum, a fatty acid or a metal salt of the fatty acid in which the fatty acid has at least 11 carbon atoms, organic peroxide and optionally a triazole. Such silicone rubber is transparent and flame retardant. Silicone rubber which does not require the transparency can be prepared from such compositions which include titanium dioxide to enhance the flame retardant properties.
