ABSTRACT:
A hot applicable, heat expandable, thermosetting sealing composition particularly adapted for use in the automotive industry is disclosed. Such a sealant comprises a styrene-butadiene rubber mixed with conventional thermoplastic resin blowing agents, vulcanizing agent, oils and thickening agents wherein the addition of an activator selected from the family of sulfonamide materials results in a sealer which can be hot applied without causing it to prematurely blow or cross-link yet remain affixed to the component until such time as it is desired to blow and cure the sealant.
