A thin self-supporting adhesive film is claimed that includes a first polyurethane and a solid surface-deactivated isocyanate.

Polyurethane adhesive film

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.
