I think there's an NPB/alcohol azeotrope that might work in a degreaser, but last I heard, they found some tumors in rats exposed to NPB, and the PEL was about 50. Tests were continuing. Of course, this might not be a problem in well-designed equipment. -----Original Message----- From: Stolar, Paul W [mailto:[log in to unmask]] Sent: Wednesday, February 11, 2004 4:36 PM To: [log in to unmask] Subject: [TN] Cleaners I have just begun re-evaluating cleaners. We are presently using an HFE in a degreaser. I want a cleaner I can use in the degreaser. Aqueous is not an option. I am not familiar with the nPB cleaners. Has anyone had bad or good experiences? What about cyclo-hexane? And other solvents?
