Epoxy Battery Sealant

A Epoxy Battery Sealant is impregnated with adhesive patches each of which is in the form of a closed loop. The surfaces of the adhesive patches rise above the surfaces of the carrier on at least one and preferably both sides of the carrier. The patches are produced by passing the carrier between a pair of applicators, the first of which has a surface that is sufficiently rigid and incompressible so that it does not deform and the second of which has a surface that is sufficiently elastomeric so that it deforms during adhesive application.
