Commercially available waterbased adhesives can be used to adequately secure unmodified TPO roofing membrane to a roof substrate only by using a two-sided (contact bond) application. Alternatively, commercially available waterbased adhesives may be used a single-sided application using TPO membrane that is modified at manufacture with an additional backing (fleece back). Disclosed herein is a water-based adhesive formulation that will bond unmodified TPO membrane to the roof with a one-sided application, saving money and increasing productivity. The disclosed adhesive is applicable by high pressure canister application, facilitating the efficiency of its use.

One-part (1K) and two-part (2K) cold bonding adhesive compositions for bonding vulcanized rubber compounds are described. The compositions can be used to bond vulcanized elastomers, such as chloroprene and buffed natural rubber, to themselves or to metal. The compositions can be free of hazardous chemicals often used in cold bonding adhesives, such as monomeric isocyanates and/or trichloroethylene or other chlorinated solvents. The adhesives also offer easy application and long pot life.
