Although five major bonding mechanisms are associated with adhesion promotion, two primary factors predominately influence the adhesion of any type of polymer to another substrate: chemical surface-to-surface interaction at the molecular level, and the wettability of the adhesive so as to enable surface spreading. Adhesion values can also be influenced by the matrix, or vehicle, that enables surface wet-out.
Adhesive bonding can be used to assemble identical materials or materials of different types; the purpose of such an assembly is to transfer mechanical loads in a given environment.
