Curing Times of P40 Exposed to Different Light Sources

Abstract

Glass casting chambers were filled with P40 resin and placed under different light sources to record curing rates and temperatures reached during the process. Results were used to assess the effects of different light sources and the method of application of that light on the curing of P40 resin. It was found that curing of P40 resin was achieved by exposure of the resin to sunlight, artificial UV-A light and mercury lighting. Fluorescent lighting had no effect on P40 resin. Curing rate was increased as was maximum temperature reached during the process when light sources were allowed unregulated interaction with the resin.
