  • Vulcanizing adhesive composition
    Patent number: 6663705
    Abstract: A vulcanizing adhesive composition comprising a copolymerization oligomer of amino group-containing alkoxysilane and vinyl group-containing alkoxysilane, a nonionic surfactant of HLB 10-16 and an acid compound is an aqueous vulcanizing adhesive composition free from an organic solvent and for use in bonding of fluororubber to a metal, which is also effectively applicable to any of polyol-vulcanizable fluororubber and peroxide-vulcanizable fluororubber, showing a good adhesiveness even to stainless steel of poor wettability toward the conventional aqueous adhesive.
    Type: Grant

  • Case for electronic parts
    Publication number: 20030008088
    Abstract: A case for electronic components comprises a metallic case and an electrically insulating exterior coating of an epoxy resin-based powder coating material comprising an epoxy resin, a phenolic curing agent, preferably poly(bisphenol A-hydroxypropyl ether) or poly(bisphenol F-2-hydroxypropyl ether) and a curing promoter, where the powder coating material applied to the metallic case as an electrically insulating exterior coating has distinguished coating film flexibility and adhesion to the metallic case without any cracking or peeling in the step to form an obturating portion of the open end of the metallic case and can be cured at a relatively low curing time for a relatively short time.
