Which Polymers Flux Well (Other Than Polyurethane)?

Which Polymers Flux Well (Other Than Polyurethane)?

Which Polymers Flux Well (Other Than Polyurethane)?

(OP)
Hi all,
I'm searching for polymers that will flux well around a copper wire. One is polyurethane. Does anyone know which other polymer coatings flux well?

Thanks in advance.

RE: Which Polymers Flux Well (Other Than Polyurethane)?

That is a complex question. Can I interpret that to mean something like "which polymers flow well when heated to soldering temperatures, are polar and possibly decompose to leave a clean solder joint".

I had a friend who made really nice polymers for solder flux and patented it. They were aliphatic polycarbonates. They are polar, flowed well, cleaned the joint and then decomposed into gases to give a clean joint. So that may be one answer if I understood the question. Got any more specifics that might help us?
