Abstract

In this method of curing epoxy resins by gamma radiation, an epoxy resin film is exposed to 1.5 mev electrons from a Van de Graaf accelerator at doses of from 1-160 Mrads. The dose rates are from 2.71 to 3.70 Mrad/min. No rise in temperature above ambient temperatures is experienced. Quantitative infrared spectroscopy indicates the oxirane absorbance, 915 cm/-1/, of the irradiated epoxy film to be about one half that of an unirradiated epoxy film, e.g., 0.064 as compared to 0.120.
