Bonding material in a solvent
I'm trying to figure out how to seal a circuit as described in this thread:
My question to you chemical engineers, do you guys know of any sort of bonding material (like epoxy) which will not dissolve in porpanol?
I'm having a tough time water sealing this circuit with my materials because they all seem to fall apart after a period of time in propanol!

Your choice of potting compound will probably be limited to RTV silicones (electronics grade only!) and epoxy. Allow the epoxy to cure normally (as you would treat your sensor).... don't accelerate the cure before testing since an accelerated cure will negatively impact solvent resistance. Plan on this component being a disposable item in your system.

hey chemisttree, thanks alot for the very informative post!
I went over to ACE last night to try to find some RTV silicone, but alas it was a shot in the dark. I did, however, find a solution which seems to be holding up.
I describe it here:
What's your take on that?
