Detection and Characterization of Water-Induced Reversion of Epoxy and Urethane Potting Compounds

Abstract

Infrared and dielectric measurements have been successfully used to detect changes in epoxy and urethane systems which soften when exposed to moisture and/or temperature. The data from these measurements show correlation with softening of the polymer systems (as determined by hardness measurements) and thus, indicates that the combination of infrared and dielectric measurements may be a sensitive means of detecting reversion in potting compounds.
