ABSTRACT:
A roofing adhesive particularly suited for use in connection with membrane roofing materials such as EPDM or neoprene is preferably compounded from butyl rubber, a cross-linking system for the butyl rubber and a tackifier. The tensile strength, elongation, modulus at 300% elongation and modulus at failure of the composition are adjusted within range by choice of components and concentration. The adhesive composition may preferably be formed into a tape for joining sheets of the membrane roofing material.
