  • Fluoroelastomer gelling agents and products made therefrom
    Patent number: 4320216
    Abstract: Fluorinated allylisocyanurates are extremely efficient gelling agents for fluoroelastomers. Blends of fluorinated allylisocyanurate gelled fluoroelastomers with non-gelled fluoroelastomers have improved processability as compared with non-gelled fluoroelastomers and blends of other gelled fluoroelastomers with non-gelled fluoroelastomers.
    Type: Grant
    Filed: May 29, 1980
    Date of Patent: March 16, 1982

  • Fluorine containing organosilicon compounds
    Patent number: RE31324
    Abstract: Addition to organosilicon compounds having at least one alkyl group attached to a silicon atom, at least one hydrogen atom being attached to the carbon atom adjacent the silicon atom, of a fluorocompound, which may be a fluoroolefin.[., a perfluoroketone,.]. or a perfluoroether having a carbon-carbon double bond in .alpha.-position to the ether oxygen atom, give fluorine-containing organosilicon compounds. These adducts may be liquid or solid and are useful as (1) lubricants and sealants for automotive and aerospace industries (2) fire-resistant hydraulic fluids, and (3) siloxane elastomers having good oil and lubricant resistance.
