Abstract
An adhesive formulation is provided that is a waterborne bonding adhesive for adhering sheet membranes that may incorporate a solid plasticizer. The formulation is fast-curing and develops bond strength rapidly after application to a substrate as the adhesive dries, when the sheet membrane is mated to the substrate. The fast-curing characteristic is important to ensure the membrane is not displaced from the surface in windy exterior applications. The adhesive is formulated to form the bond between sheet membranes to substrates that illustratively include, steel, wood, concrete, roof boards, insulation, and fiberglass mat roof boards.
