Description
A roofing adhesive adhesive particularly suitable for use in connection with membrane roofing materials such as EPDM or neoprene is a compound of butyl rubber, a cross-linking system for butyl rubber and a toughener. Tensile strength, elongation, modulus 300% elongation and modulus at failure of the structure are adjusted within the range depending on the choice and concentration of the constituents. The adhesive composition can preferably be formed into a tape for attaching sheets of membrane roofing material.
In the adhesive compositions and particularly in the field of adhesive compositions used in connection with membrane roofing materials such as EPDM (Ethylene Propylene Diene Monomer) and Neoprene. The adhesive composition can be formulated in a single layer to form a ply tape or applied to a strip of membrane roofing material to form a cover strip.
