Abstract
The use of microwave energy to heat and cure adhesives, resins, and other polymer precursors is becoming a disruptive and uniquely useful technology. Restrictions in chemical processing are being modified or removed with benefits in product properties and assembly reliabilities. To understand the source of these advantages, it is helpful to review the nature of the inductive polarization effect of electromagnetic energy on electron distribution in molecular orbitals; the kinetic effects of induced bond rotation; the thermodynamic contributions of entropy; and the unique contributions of the microwave wavelength. All of these factors contribute to fundamental changes in the nature of adhesive and resin polymerizations, as well as the chemical, thermal, and mechanical properties of the end products. For a good review of fundamental microwave theory, the 1983 book Industrial Microwave Heating by Metaxis and Meredith is recommended [1].
