Coupling agents are additives that increase the interaction of one material with another. The usual coupling action is based on primary or secondary chemical bonds. It is particulary useful in coupling fillers or fibers to a polymeric matrix.  Examples include silanes, titanates, zirconates and aluminumates.  Coupling agents may promote adhesion, catalyze reactions, improve dispersion, rheology, impact strength, prevent phase separation and inhibit corrosion. Coupling agents may involve six functions, hydrolysis coupling reactions, catalyzed reactions, functional groups, thermoplastic functions, crosslinking functions and mixed functions. (RDC 7/28/2008)
