Sorry people - I was thinking of vapor phase reflow NOT cleaning.
My mistake.
Would a company like Zestron have anything to go into a degreaser? www.zestron.com
Sure it is not Friday?

Steve,
When / if it gets dirty or contaminated, one sends it back to be reclaimed like high quality vacuum pump oil.
It used to be that 3m sold the fluoroinerts, then Galden, then Ausimont. I believe that it is now Solvay Solexis - but they still retain the Galden product names.
Check out this web page for details http://www.solvaysolexis.com/Galden.htm

Hi Gary!
You weren't kidding when you said it was expensive! I checked, and it was $761.41 for 5-gallons! Wooo-dogies!
Is there anything else out there? Anyone?

Steve,
Asahiklin (AK-225) is what I used at my last company. There is a variant of this that has VOC under what the EPA limits for reporting purposes. It works well but is expensive.
Thanks,

Hi Brian!
I read everything at the link you provided, and I am giving it thought. Our degreaser doesn't have an extended freeboard, so that would need to be added if we were to go to Ensolv.
Let me ask you this, what would you use in a vapor degreaser? I did a search on vapor degreasing chemicals and almost everything that I came up with were nPB based...what else can I use?

I do not recommend EnSolv, as it contains nPB. You can learn a little about its environmental and H&S issues - and both require serious thought - at http://www.cypenv.org/worldenv/files/npb.htm.
If you must use it in a vapour degreaser, the recommended practices to reduce emissions include a deep (1½ times the opening diagonal) refrigerated freeboard, automatic sliding doors, small baskets to prevent pistoning the vapour out of the machine, draught-free environment, automatic hoist to respect freeboard dwell times and prevent brusque movements, minimal disturbance when filling/emptying machine and only when cold etc. I would also recommend operators wear badges so that their exposure can be constantly monitored. Listen to the operators for any unusual symptoms. The operators should wear protective clothing, bearing in mind that dermal uptake of nPB can be significant.
UNEP discourages the use of nPB wherever possible.
