ABSTRACT:
Adhesive compositions are shown made from mixtures of EPDM and halogenated butyl rubber compounds. The mixture may either be dissolved in solvents and applied as adhesive solutions, or they may be incorporated with tackifiers and formed into adhesive tapes. The compositions are particularly useful in adhering strips of EPDM membrane roofing to each other; however, they may also be used as protective coatings and linings.
