  • Patent number: 3986629
    Abstract: A sealant composition for sealing a can end comprises a mixture of about 15-30 percent by weight of a hydrocarbon resin melting in the range of about 85.degree.-125.degree. C and comprising 100 weight parts of at least one of natural and synthetic rubber and 30 to 120 weight parts of a hydrogenated hydrocarbon resin tackifier prepared by polymerizing a cracked petroleum fraction boiling between -10.degree. and 280.degree. C and containing unsaturated hydrocarbons at least 50 weight percent of which is at least one of aromatic olefins, cyclic olefins and cyclic diolefins, and hydrogenating the resultant polymer to a hydrogenation rate of at least 40 percent; about 1-8 percent by weight of stearic acid; about 0.1-1 percent by weight of butylated hydroxy toluene; about 0.1-1 percent by weight of polyparadinitrosobenzene; about 20-40 percent by weight of paraffin wax; about 1-5 percent by weight of zinc oxide; about 0.
    Type: Grant
    Filed: September 24, 1975
    Date of Patent: October 19, 1976
    Assignee: The Southland Corporation
    Inventor: Henry M. Singleton
  • Patent number: 3959206
    Abstract: Aqueous can end sealant compositions substantially free from volatile organic solvents, setable at ambient temperatures and based upon relatively high molecular weight SBR latices are disclosed. The compositions are virtually free from the discharge of dangerous volatile organic solvents during the period of setting, yet become solid at ambient temperatures and are suitable for can formation by double sealing, particularly aerosol cans to contain food or non-food products.
