Abstract

Differential Scanning Calorimetry(DSC), Torsional Braid Analysis (TBA), and Fourier Transform Infrared Spectroscopy (FT‐IR) were used to study the cure characteristics of an epoxy system that utilized a sterically hindered amine curing agent. The apparent activation energy was found to be 13.3 kCal./Mol. by DSC and 12.8 kCal./Mol. by FT‐IR. Resin volatility hindered useful application of conventional TBA techniques. The resin was found to react to a partially cured (52%) state at room temperature and then vitrify. Samples stored for a two‐month period showed no advance in cure state. Subsequent application of heat caused resin devitrification and advance to a more fully cured state. The isothermal curing behavior was studied in a temperature range from 100° to 150°C.
