Thermally stimulated currents in cured resin of electrostatic powder coating

Thermally stimulated currents (TSC) were observed for commercial powder paints partially cured at different temperatures and different times. A higher temperature band between the two TSC bands observed in the cured paints shifted with regularity towards the high temperature side, depending on the cure temperature and time. Activation energies for the cure processes were derived from phenomenological analysis of this TSC peak shift on the basis of a simple model.
