ESC waterproofing by total encapsulation

[DISAR]

MGM has a new option for ESCs, total waterproofing by encapsulation. I have one and is working great.

I want to do the same thing for a Hydra HV240, since there are enough cooling plates between the boards. My question is, has anyone done that and with what material? I have a 24hr epoxy which says "safe to waterproof electronics", tested it in a receiver and works well.

Yep. I've seen some guys use J-B weld as well.

Ok, thanks!!

Of course this method makes the esc unrepairable and out of warranty but no problem for me, I only want 100% waterproof

that's what I've done on my cheap Mystery and Swang 2 years ago!

with what material?

I did it with bathroom silicon!

many thanks!

Very poor idea!!! Many silicones release acetic acid as they cure, which corrodes electronic parts like mad. This is what causes the distrinctive odor of these adhesives. If you choose to use silicone, make certain it does not release acid!

Oh dear God! That would suck!

I have a half dozen or more receivers encased in pure clear GE silicone. All less than 6 months old. I've been planning on doing the same with some ESC's, but will need to take a better look at the curing process.

I chose silicone because it is removable, arduous task but removable if needed.

OK, I'm good. The container says "methanol and ammonia" are released during the curing process. It's also 100% pure silicone.

Tell me more about the epoxy for the ESC's. I have a few that I would like to encase as well. I was considering thermal epoxy to help dissipate heat...

I was thinking about fabricating a small plastic box with holes/grommits to fully waterproof an ESC. Has anyone tried that approach? I imagine Tap Plastics could easitly fab something like that,

I recall a thread about cooling that used a little tupperware bowl and some non-conductive oil...

My buddy made a box for a castle esc, worked great. ESC finally bit the dust though.

I don't think 100% silicone would give you the acid issue. I think that comes into play when you run that stuff that is part latex...

I think they use it in the partial acrylic mix, the hard tub and tile caulk.
