Anyone used raytec Magic Gel to pot electronics?

Looks like a good option for potting for waterproofing electronics , allowing possible re-entry, and not too expensive - anyone tried it ?

Looks like they're promoting it more for electrical uses - filling junction boxes etc.

Yeaah, a guy named Ray tried to give me some magic gel once. It didn't end well and I don't like talking about it.

It does look like a neat gel, but of course could only be used inside an enclosure, and even though it has a low viscosity, it does appear to not turn into a gelatin or solid from what I can see. To me that means while it's nice to take it out, perhaps it would be a nightmare to clean out of stuff it's not supposed to be in? Another wonder if it does flow and how fast in it's cured form.

I've used it on a research project putting wireless GPS trackers on wild horses in Spain. We used it both for the water-proofing aspect but also to give some degree of shock-proofing (the design had some wired and soldered components including the battery connection). The devices held up well despite getting knocked into trees by the horses trying to get rid of them, and I don't believe we had any moisture issues with any of the devices that we collected at the end.

The working time can be a bit short when you're filling a lot of devices at once (we tried batches of around 20, which was a bit much), and any spillage will leave a very slippery residue on the floor that is exceedingly difficult to clean up (seems to be silicone based). Probably best to put down a tarp first.

Why not get something from a real professional electronics chemical supplier like MG Chemicals?

Because it's easy to buy in small quantities and appears to have some good attributes.

Raytech seems to be an electrical box manufacturer, not a professional chemical manufacturer.

So they probably have it manufactured by someone else - so what?

It's silicone resin

Interesting name and box graphics, it makes it look like something you would have given the kids to play with on the kitchen table.

Actually, Magic Gel is what they used to rub their skin to numb it before injections (and therefore what I ask for before a Cystoscopy, but that's another story!  ).
