Understanding the formulation and performance of adhesive systems requires a combination of surface chemistry, rheology, fracture mechanics, and structural design. A number of different rheological measurements can be invaluable to the adhesives chemist. Today, rheology is used to predict behavior in application processes such as coating, calendering, and extrusion; to follow adhesive cure and aging; and to characterize bond performance. This paper discusses a number of examples where rheology has helped to solve adhesives process and product problems. Nearly all of these adhesives are polymeric or react to form polymers. Rheological methods are particularly sensitive to the size and motion of large molecules. The discussion is presented under headings - hot melts; solvent-based adhesives; structural adhesives; pressure-sensitive adhesives.
