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? Steve Bartlett Earl T. Hackett, Jr. wrote: .... 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?
