Nice. Do you know something about isolative/conductive properties of Plasti Dip?

[homefire]

None Conductive. Can also be used as protective coating on under side of coil housing like coil skid cover.

Yes, probably this "Plasti Dip" suit better to our coil potting needs:

Actually it's the same stuff. Just thickened. Plasti Dip does contain Methyl Ethyl Ketone that likes to eat some plastics but I've not found it a issue using thin coatings.

http://www.ebay.com/itm/132150037962?ul_noapp=true 12 oz. Spray Can TOTAL GROUND Carbon Conductive Coating (MG Chemicals 838-340G)
what it is i do not know. link was sent by ebay on my email.

[sinclairuser]

Are you use it for pulse technology MD only or also for VLF?

hi used it on ;pi coils both mono and ib, and used it to refill an old whites coil after repair(vlf).

Somebody wrote that hot glue is heavier than epoxy, but i just saw that hotglue has a density of 0,98 g/cm³.
Epoxy has about 1,2 g/cm³, i think i will use hotglue for my second coil.

What about powder from styrodur plates instead of microballoons?
Costs nothing and is light.

What is styrodur? I'm assuming it's expanded polystyrene.

Yes, Styrodur is brand name of expanded polystyrene.

You do do not need to pulverize it, cause it is available in small cheap balls too (outer epoxy layer should be armored by some sort of fabric):

It may be worth a try using it as a filler in resin but there could be problems with the beads floating to the surface.
Also, if the polystyrene were powdered, the resin could be absorbed into the voids, greatly reducing the filler effect.
It can only be used with epoxy resin as the beads will quickly dissolve in polyester.
I agree with WM6 about the need for a composite surface layer but this could end up rather bumpy if laid straight over the bead/resin mix which would be difficult to sand smooth.

[WM6]

You ca try to fill coil housing by Pur-Pen (polyurethane construction filler/adhesive in spray dose),
cut it under inner housing edge to let some space for final epoxy layer (better armored by fabric).

[BKY1337]

I tried it, it works.

The pieces doesnt float if you use enough from it. And you can make more layers to be sure.
The styrodur doesnt dissolve in the resin and its light. I also used glassfibers at the outter arms.
