Q. We are chemical strippers and have a client who has a number of alloy units who wishes to remove a Teflon ring from one end. Is this possible? D.S.


A. I think this is the first time I have ever received a question from New Zealand. Thanks for reading! If I understand you correctly, you are trying to chemically strip a Teflon ring that is inset into one end of a metal object. Unfortunately, that chemical compatibility and inertness is what makes Teflon so desirable. The only thing I could find in a chemical compatibility chart that seemed to present a problem with Teflon is diethylamine. It is possible that the combination of solvents that are used in many “heavy duty” paint stripping mixtures (toluene, xylene, naptha, methylene chloride) in a hot tank could budge this, but that is a big could. It does not look like it’s very likely that you will be able to do it, though.
