A moisture curable polyurethane hot melt adhesive composition and a process for making the same are disclosed. The moisture curable polyurethane hot melt adhesive composition includes an isocyanate-terminated polyurethane prepolymer that is the reaction product of a diisocyanate monomer component that includes at least 20% by weight asymmetrical diisocyanate monomer based on the weight of the diisocyanate monomer component and symmetrical diisocyanate monomer, at least one polyol having a number average molecular weight greater than 1000 g/mole, a monofunctional compound that includes one isocyanate-reactive group and has a molecular weight no greater than 400 g/mole, and a multifunctional compound that includes at least two isocyanate-reactive groups and has a molecular weight no greater than 400 g/mole.

Disclosed is an aqueous adhesive composition including a surface-deactivated solid isocyanate and a blend of two different polyurethanes. A method of making an article that includes a coated adhesive layer and article made thereby are also disclosed.

Reactive adhesive with enhanced adhesion to metallic surfaces

Disclosed is a self-supporting, heat curable adhesive film including a surface-deactivated solid isocyanate and a blend of two different polyurethanes. A method of making an article that includes the adhesive film and article made thereby are also disclosed.

Reactive film adhesives with enhanced adhesion to metallic surfaces

Disclosed is a multi-layer adhesive film including a heat curable adhesive film and a first tacky adhesive composition disposed on the first major surface of the heat curable adhesive film. The heat curable adhesive film includes a surface-deactivated solid isocyanate and a polyurethane that includes functional groups that are reactive with isocyanate. A method of making an article that includes the multi-layer adhesive film and article made thereby are also disclosed.
