Abstract

An adhesive composition is provided for adhering together roofing materials such as EPDM rubber and thermoplastic polyolefin (TPO). The adhesive composition includes a rubbery polymer comprising a blend of a thermoplastic block copolymer selected from the group consisting styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene-butylene-styrene, styrene-ethylene-propylene-styrene, styrene-ethylene-propylene, ethylene-propylene, and combinations thereof, and a paraffinic hydrocarbon polymer. Roofing articles incorporating the adhesive composition are also provided. The composition is a pressure sensitive adhesive that allows roofing articles to be applied in a peel and stick manner.
