  • Publication number: 20050224247
    Abstract: A protective cap for adhesion to a substrate including a substantially flat base sheet, a dome extending outwardly from an obverse side of the base sheet and forming a cavity in the opposite side of the base sheet with the cavity sized for substantially encapsulating a connector. The cap also includes a semi-tubular shield extending outwardly from one side of the base sheet that defines a channel in the opposite side of the base sheet extending from the cavity toward the periphery of the base sheet, and an integrated primer layer comprising a pressure-sensitive adhesive and attached to the reverse side of the base sheet for application to the substrate.

  • 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.
