Subject: [LF] Potting Mix (O.T)



Hello,



I wish to pot a small automotive module for which I am assembling 

very small volume.

I used what was on hand, a fibreglass polyester resin, for my first 

prototype without

incident.



Can anybody comment on the appropriateness of continuing to use such 

resin as while

this is somewhat of a backyard exercise for some ignition modules, 

for which I found the

resin readily available and cheap, I am keen to pursue reliability. I 

have no knowledge of

whether such a resin has any negative influence on electronic 

components, FR4 board

and PVC wires. The alternative Dow corning materials seem rather

expensive.



Cheers, Colin
