Earl,
How about an epoxy? Even a metal-filled type might be non-conductive.
I have successfully used "Plastic Steel," a two-part epoxy, to make
insulating bushings when I was 2-railing some old, uninsulated model
railroad wheels.

Alternatively, maybe a redesign of the coils is in order. What size
wire are the coils wound with, and do you know how many turns?

I have some electrical coild about 0.5" dis. x 0.75" long. They are
being used to power electromagnets at about 5 VDC and 0.6
amp. They appear to be getting a bit on the hot side when run
continuously. There are some heavy aluminum structural
components around them that would make fine heat sinks - if I can get
the heat to them.

Does anyone know of a good thermal conductive material that will fill
gaps from 0.05" to 0.1" wide?
