Abstract

This chapter discusses adhesives, which are joining systems based upon surface attachment, i.e., adhesion. The adhesion is the physical attraction of the surface of one material for the surface of another. These physical attractions are the same physical attractions that one normally associates with descriptions of the states of matter, i.e., van der Waals and electrostatic forces. The science of polymeric adhesion is concerned with the description of two distinct steps: the formation of an adhesive bond (‘‘adhesive bond making’’) and the physical strength of the adhesive bond (‘‘adhesive bond breaking’’). Adhesive test methods and their test results are related to but are not the same as other polymer property tests. In general, adhesive property tests are ultimate properties measured at the failure load of an adhesive joint. Adhesive joint properties are certainly related to adhesion but are primarily due to the physical properties of the adhesive and the physical properties of the adherends. The type of adherend or backing will be described, if at all possible. The adhesives can be classified in a number of ways. They can be classified according to chemistry (e.g., epoxy versus neoprene), according to application method (e.g., hot melt versus spray applied), or according to strength. The choice of adhesive for a particular end use is based upon criteria of modulus, ultimate strength, fracture resistance, compatibility with the adherend, resistance to adverse environments, and considerations of economy. The adhesives including structural adhesives, hot-melt adhesives and elastomer-based adhesives, are presented in order of decreasing strength.
