depending on the type of circuit needing encapsulation (high vs low voltage, although this can work for hv if careful), using quality glass bead (the type for "sand" blasting) can be used as a encapsulating/insulating material, and/or a filler before using expensive high voltage encapsulating epoxy. it flows well into complex spaces/voids, etc. i use fine glass bead unpacked as a filler before using a quality epoxy to encapsulate (saves epoxy). my stuff is all "low" voltage. at 60vdc with electrodes at 0.1mm apart i was able to achieve 0.0uA (0.1uA is the best resolution my Fluke can read). i have not done any testing with higher voltages yet.
