All the epoxy resins that I have seen are poor insulators. Maybe 
good enough for Tesla coil insulation, and even advantageous for
safely draining static charges. Epoxy doesn't retain static 
charges for long (seconds) periods. It can't even be electrized by
friction. A big no-no for electrostatics.
