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 0.25-1 percent by weight of lamp black; about 5-15 percent by weight of titanium dioxide; about 10-30 percent by weight of polyisobutylene; and about 10-20 percent by weight of at least one of butyl rubber, styrene-butadiene rubber and styrene-isoprene rubber.
