Malyar This theory postulates that the interface zone is plastic, allowing stresses between the polymer and mineral surfaces to self-relieve without bond rupture. Internal stresses are thus reduced. It has been suggested that in the case of a silane, the film is too thin to allow this [11]. However, it is possible that the presence of the coupling agent might cause preferential adsorption. Credence for this view is given by the number of

workers who report that the amount of adhesion promoter used is critical and that excessive usage may result in adhesion failure [16,17].
