  • Permanent antistatic coating and coated polymeric film
    Patent number: 5925447
    Abstract: A thermoplastic film coated with a permanent antistatic composition to form an antistatic coating thereon, and a method for priming a thermoplastic film with the antistatic composition. The antistatic composition comprises: from 2 to 11% by weight of an antistatic copolymer; from 0 to 0.45% by weight of an antistatic compound; from 0.25 to 2% by weight glycidoxy silane; from about 0.3 to 2% by weight spherical silica particles having an average diameter of 10-100 nanometers; and water, or a mixture or water and organic solvent, wherein the total weight percent of all components equals 100%.

  • Vermicular expanded graphite composite material
    Patent number: 4265952
    Abstract: The present invention relates to a vermicular expanded graphite composite material and to an improved method for preparing such material by blending vermicular expanded graphite with a corrosion resistant resin dispersed in a carrier, vaporizing the carrier, and heating the composite material to sinter the resin. Compressed forms of the composite material are useful for protecting corrosion vulnerable substrates.
