Abstract
Abstract
In this paper, the epoxy value of epoxy resin TDE-85 was measured by proton nuclear magnetic resonance (1H-NMR) spectroscopy and tetraethylammonium bromide titration. Comparisons of the measurement results and repeatability of the two methods show that the NMR spectroscopy can be used to measure the epoxy value of epoxy resin TDE-85. However, because of the high requirements for sample purity, when testing TDE-85 containing impurities, the measurement repeatability of NMR spectroscopy is worse than that of tetraethylammonium bromide titration.
