The tape includes a backing, a reactive layer on the backing, and a pressure sensitive adhesive on the reactive layer. The reactive layer includes sulfur and a rubber at least partially crosslinked with polysulfide bonds. The pressure sensitive adhesive includes a hydrocarbon elastomer that is at least partially crosslinked and a tackifying resin. The process includes applying a dispersion of the rubber and sulfur to the backing, drying the dispersion to provide the reactive layer, and applying a pressure sensitive adhesive composition comprising the hydrocarbon elastomer and the tackifying resin as a hot melt on the reactive layer to provide the tape.
