  • Primerless pipeline coating tape
    Patent number: 5516584
    Abstract: A article for wrapping objects comprising a plurality of layers, including a first layer of a wrap material, an intermediate layer of an adhesive material and an inner layer of a solids material, said article providing resistance to cathodic disbondment from said object at least equal to an adhesive bearing wrap applied with a solvent based primer.
    Type: Grant
    Filed: August 3, 1994
    Date of Patent: May 14, 1996
    Assignee: T C Manufacturing Co., Inc.
    Inventors: John Blitstein, David McVey, Ken Konopka, Donald H. Kathrein
  • Corrosion-resistant coating composition containing hollow microballoons
    Patent number: 4403048
    Abstract: A fluoroelastomer hollow glass microsphere coating has been found to provide new and unexpected corrosion resistance to metal surfaces for protection against severely corrosive environments. The coating comprises a fluorocarbon elastomer and 3-50% by volume of hollow glass microspheres or microballoons having a size in the range of about 2-300 microns, preferrably 20-200 microns. The hollow glass microspheres or microballoons substantially increases the corrosion resistance of a fluoroelastomeric liquid composition, yielding new and unexpected thermal and chemical resistance, particularly when the coating composition is applied in two or more layers.
