Abstract
Disclosed is an adhesive composition comprising an acrylic resin and an oligomeric resin having a reactive group and methods for making and using the adhesive composition in roofing membranes. The adhesive composition is thermally cured to form an adhesive layer. The adhesive composition may be applied to a membrane, such as a single-ply membrane, and then thermally cured. The single-ply membrane may then be adhered, via the adhesive layer, to a substrate, such as a roofing substrate.
Claims20
An adhesive layer comprising an acrylic-based polymer crosslinked by thermal heating with an oligomer having a reactive group, wherein the adhesive layer has a (shear adhesion failure temperature test (SAFT) value from 80 to 110° C. and a Tg from −40 to −30° C.
