Non-reactive Adhesives

Polyurethane solvent borne adhesives consist of a high-molecular-weight hydroxy terminated polyurethane dissolved in a solvent. They are prepared by reacting a high-molecular-weight polyester diol with a diisocyanate. The polymer solutions are applied to both surfaces to 

Aqueous dipersion adhesives are high-molecular-weight polyurethanes dispersed in water. They are applied and used in exactly the same manner as solvent-borne systems with the benefit of not using hazardous or flammable solvents.

We now present a theoretical model suited to non-reactive adhesion, which describes the electronic states at the interface between a thick metallic overlayer and an oxide, as a function of the metal and oxide characteristics (Bordier and Noguera, 1991 1992).
