Steve, I have used conformal coat thinner that is about 80% MEK. It does an excellent job of cleaning TakPak, Loctite 3621, 3609, 3607 and other epoxies. Try that first. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Thursday, April 02, 2009 8:09 AM To: [log in to unmask] Subject: [TN] Solvent for cured cyanoacrylate adhesive Mornin' all, I have a question for the chemists out there about the solvent used to clean-up cured cyanoacrylate adhesives. Loctite sells a solvent called 768 X-NMS Solvent that works pretty well, but it is expensive. Anywhere from $20.00 to $37.00 for a little 1.75 ounce bottle depending on where you buy it. I do know that it is composed mainly of nitromethane with a little bit of toluene according to the MSDS. My question is; I can get a gallon of nitromethane at a high-performance auto parts store store nearby for $50.00 a gallon, would pure nitromethane do the job? Or do I need to add the toluene as well? The MSDS gives a range of percentages of both components, but is kind of vague: http://www.rshughes.com/images/products/docs/zwNFyUtpQskOxsrawO1uew.pdf I'm just trying to save a little money is all...
