  • Composition for removal of ionic salt deposits
    Patent number: 5604191
    Abstract: A composition and method for the removal of ionic salt deposits from a surface using an organic solvent of low polarity and a complexing agent. The complexing agent is chosen from a group which includes podands, cryptands, and coronands. The method provides nearly complete removal of ionic salt deposits with a single washing of the surface with the low polar cleaning mixture.
    Type: Grant

  • Composition and process for preventing electrostatic discharge
    Patent number: 5425995
    Abstract: The invention provides for a process of using a static dissipative, polymeric composition to prevent electrostatic discharge. The static dissipative, polymeric composition is both humidity independent and water insoluble. The present invention also provides an article comprising a substrate to be protected from electrostatic discharge.
