Disclosed are curable sealant compositions for coating a conductive bushing for a lead-acid cell or battery having positive and negative plates disposed within a container and a cover, the conductive bushing being molded into the cover and providing electrical communication with at least one of the plates, the bushing presenting an interface with the exterior of the bushing and the cover. The sealant compositions comprise a sealing elastomer in an amount from about 1 percent to about 15 percent by weight. In accordance with the invention. The sealant composition is a terpene solvent, preferably a cyclic terpene and more preferably further comprises a reinforcing agent in an amount of about 1 percent to about 15 percent by weight. In use, at least a portion of a bushing is coated with the sealant composition, and the sealant composition is cured. The bushing is insert-molded within a nonconductive plastic substrate to form a cover for a battery or cell, such that the sealing elastomer seals the interface between the bushing and the substrate. |
