Homebrew PCBs

If I were building an etching tank I would contact Master Bond to ask
what adhesive/sealant they would recommend. I'd be surprised if they
don't have a solution.

At last week's Dorkbot Bristol, we had a talk on making PCBs
(by UV exposure method) and the speaker mentioned this. He'd
used silicone sealer on an etching tank, and found that it had
leaked. The etchant had a warning on the label about not using
silicone sealer in contact with the liquid. But no-one knew
why this should be, chemically speaking.
