The Curing of a Bisphenol A Type Epoxy Resin with 1,8 Diamino-P-Menthane.

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 which utilized a sterically hindered amine curing agents. 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 percent) 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 C to 150 C. (Author)
