At 15 KV, no varnish, epoxy, or other coating in reasonably thin layers
is going to be adequate to hold off that kind of voltage.
You have to design your transformer intrinsically to provide that
voltage standoff, with an insulating bobbin for the windings of
sufficient size, conformation, and dielectric strength to keep the HV
away from the grounded core. Applying a few thousandths of varnish is
not going to improve the protection appreciably.
It sounds like you are reinventing a 60 mA neon sign transformer. Would
it not be easier and faster to pick up one ready made off eBay, or from
your local neon sign shop?
