EPDM sealing compound and lid formed by applying the same

摘要

A sealing compound comprising an aqueous dispersion which contains a rubber component of an ethylene propylene nonconjugated diene copolymer rubber as a chief component, a vulcanizing agent, a vulcanization accelerator and a filler. The sealing compound has excellent resistance against the contents that could not be handled with the metal container sealing compositions comprising the aqueous dispersion solution of the NBR and SBR, and exhibits excellent sealing performance and durability even when used for such contents. The sealing compound can be preferably used for the double-seam sealing being applied to the lid so as to be interposed between the lid and the container to seal the content by double-seaming the container with the lid.
