Adhesives for low surface energy materials

A method comprising:

• obtaining an adhesive,
• wherein the adhesive comprises a styrenic block copolymer and a process oil;
• obtaining a roofing membrane,
• wherein the roofing membrane has at least one untreated surface,
• wherein the at least one untreated surface has a surface energy of 40 mN/m or less;
• applying the adhesive to a roofing substrate,
• wherein the roofing substrate is selected from the group consisting of at least one of a plywood substrate, an underlayment, a roof deck, or any combination thereof;
• and
• applying the roofing membrane to the adhesive,
• wherein the adhesive is located between the roofing membrane and the roofing substrate,
• wherein the adhesive directly contacts the at least one untreated surface of the roofing membrane and the roofing substrate;
• wherein the adhesive adheres the roofing membrane to the roofing substrate;
• wherein the adhesive, when applied at a thickness of 27 mils to 33 mils and when located between the roofing membrane and the roofing substrate, exhibits a peel strength of at least 5 lbf./ft., as measured by lifting the roofing membrane from the roofing substrate at 180° and at 77° F.
