Waterproofing Esc's - Advice Needed.

[Fruity]

Guys,
I have just been sourcing parts and am about to start building a Twin H&M Maritimo. I have 2 x 120amp Hextronics ESC's that I want to use, I will make cooling plates, but:

What is the best to coat them in, I have heard of Conformal Coating, what is it? can I buy it in a spray can? from where?

Any idea's or good results for Watercooling and Water proofing these ESC's, please pass on your knowledge.


Thanks....Tim.

hey tim
look on the ose home page under building supplies. there is a waterproofing section with a few items. not too sure about the dip coating stuff though? the corrosion x looks like the ticket to me. 8.95 imo some of this stuff you can pick up about any hardware store.
check out the tips and info section of the home page as well for some ideas about water cooling the esc. good info on adding a water cooling plate to an esc that doesnt come with one. i think there is also info on maybe covering esc with the epoxy listed at ose too.
good luck

Epoxy? One application and you're done, forever! I would say, check the connections before applying as you don't want the steering to work the throttle. Or use hatch tape and seal all the bolt holes with silicon.

Hi Tim

I have the same hextronic 120amp ESC and it has been very good to me, I made cooling plates from soldering .5mm brass sheet into the shape of the oem heatsink plates, leaving them hollow so water actually circulates inside the plates, the plates end up being about 3-4 or so mm thick., I coated the fets with thermal grease then put the plates in and coated the entire esc with dp270 epoxy. I have had this esc for about 3 or so years now and it still goes well and handles 6s no issue.
