David Whalley,

I got out of vapor phase right when Ozone Depleting Chemicals (ODC's) were
being phased out. However, I had investigated using the 3M vapor phase
chemistries which were "environmentally friendly". From what I've heard,
these chemistries were found to be acceptable but I have no first hand
knowledge on their performance. I do know that these fluids were very
expensive.

You can get information on these chemistries from their website:

Here is another vendor which manufacture vapor phase soldering fluids, for
comparison sake:

Good Luck and Happy Holidays.
