Ran into a new product while purchasing plastic resin for my next project. Thought I would share this. Looks simple, just poor it in.

EpoxAcast® 650 It is used for electrical encapsulation to extend the life cycles and enhance the performance of potted electronic devices.

EpoxAcast® 650 Mineral Filled Casting Epoxy Resin | Smooth-On

 

Wonder what that does heat wise

 

It is an already enclosed caseing, surrounded by conductive metal, which produces static. I'll bet it works just fine.
"An encapsulant, also know as a potting compound or casting resin, is a liquid resin system comprised of either one or two components that is poured over electrical and electronic components. It can either be in an enclosure such as a plastic shell or case or it is poured into a mold holding the components where the cured material acts as the shell. These encapsulating resins are designed to electrically insulate and environmentally protect the components from moisture, chemicals, mechanical/thermal shock and vibration. This protection allows these electronics to be used in many more applications ensuring reliable, long-term performance."

Everything I have read so far shows that this material is excellent in heat dissipation.

 

I have used that stuff to waterproof my RC cars and planes electronics before, it works great. I never had any thermal issues using it, my plane speed controller without it would run about 120* with or without it. You can pick it up at most hobby shops I just never thought of using it on the disco you got me thinking now.....

 

sweet.

 

I WAS AN aVIATION ELECTRICIAN IN THE NAVY.

ALL CONNECTORS ON OUR AIRCRAFT HAD POTTING MATERIAL SEALING THE CONNECTOR AND MOST ELECTRONICS HAD SOME TYPE OF ENCAPSULATION.

GOOD RECCOMENDATION I THINK.

 

why not dunk the case in dip it...it is the case bubbleing away that usually allows corrosion and water in. That might be silly but that is what I was thinking

 

you could always make an otter box for it.....

 

That would be mean to the otters. Why would you treat an otter like that?

I was considering re-routing the wiring and mounting the ECU inside the vehicle.

 

Now we know why the nauga's hide !

you know re routing probably wouldn't be very hard with the wiring right there you could probably put it under the glove box somewhere hmmm
