We've had success using a Dow Corning product, Sylgard 170 Silicone
Elastomer.  This product is also available in a "fast cure" version
(less than 10 minute cure vs 24 hours).  This product is distributed
through Ellsworth Adhesives.  We use a 210ml duocartridge with a static
mixer, as this limits the amount of material that is wasted.
Good luck.

Subject: [TN] Looking for Potting Compound guidance

Our customer has requested that our product be "potted" to help it
survive longer in an "automotive" environment.  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.

Thanks,
Carl
