Exactly. There is no reason to use anything too aggressive with 1B31.
Acrylics are very weak solvent wise. Now if it was fully cured UR, that's a
different story.

While I agree with Patrick that this stuff works, it is Tetrahydrofuran, a
nasty material and very aggressive. And if you have the possibility of
operators mixing soldering irons with THF, you get some frightening
breakdown products. We used to use these, but got away from it completely.
Straight toluene or xylene will strip 1B31 pretty effectively and is much
less costly or hazardous than THF, especially if you are doing a few hundred
assemblies. And you have some good recommendations for companies that will
do this for you.

Ioan,
When we need to remove conformal coatings for repairs we use Conformal
Coating Remover from Trace Technologies, we get it from TechSpray in
Amarillo Texas 806-3728523 www.techspray.com
MSDS (Material Safety Data Sheets) can be found online. Very effective
for removing HumiSeal and others.
We have it in 1Qt. Bulk and in 12.5ml pens, great for spot application.
Pat

Dear Technos,
I'm looking for a facility able to strip 1B31 from a few hundreds of boards
preferably in Eastern Canada or US New England. On or offline answers
appreciated, no sub contractor is a priori disqualified, even if in CA.
Thanks,
