View License Agreement A review of the recent progress in development of HPLC techniques for the analysis of epoxy resins is presented in this paper. Three categories of epoxy resins, i.e., liquid, solid, and novolac epoxy resins, are included in the discussion. For analyzing oligomers and other components of these resins, HPLC has been recognized as the best choice based on speed, reliability, and accuracy of analysis. Successful resolutions of major components in the epoxy resins have been reported based on using reversed phase HPLC, UV detection, and acetonitrile/water or tetrahydrofuran/water solvent mixes and gradient elution techniques. Different components of the epoxy resins can be responsible for the success or failure in the performance of a coating formulation. Examples are given of some component identifications and their possible relationships to epoxy coatings properties, such as adhesion, viscosity, and flexibility. | ||
