Hi Carl, I'm not sure of the cost but at the last company I worked for we used Emerson and Cuming 2850 FT for potting electronic modules for aircraft. It worked really well and wasn't too bad to work with.

Our module is in a plastic box (black ABS, 80 degree C), and controls a small diesel engine in an enclosed area. I'm looking for suggestions for a good potting compound that is: 1. "right for the job" 2. low cost 3. easy to use 4. not hazardous 5. makes sense to use in relatively small batches (100 units at 5 ounces each) Can any TechNetters suggest potting compounds that they are happy with? Fatherly guidance and old war stories will be greatly appreciated.
