It evaporates easily and can form explosive mixtures in air over= a wide range of concentrations. Not to mention that it would degrade/destroy printed circuit boards; acetone breaks down the resin that binds the glass fibers in the laminates! Not as fast as n-Methyl-2-pyrrolidone, bus fast enough. I remember this special non-condictive 3M fluid that can be used to cool electronics. A group of hackers dunked a complete PC minus the case and pow= er supply in this stuff. The fluid itself was cooled with liquid nitrogen. They everclocked it something wicked. Not very practical though. :-) Roland --=20 R.F.Smith http://www.xs4all.nl/~rsmith/ [plain text _non-HTML_ PGP/GnuPG encrypted/signed email much appreciated] pgp: 1A2B 477F 9970 BA3C 2914 B7CE 1277 EFB0 C321 A725 (KeyID: C321A725) --FL5UXtIhxfXey3p5 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iEYEARECAAYFAkqVmdMACgkQEnfvsMMhpyWt+ACcDYO7P9uPS9M9l8NoEsnstQs2 zXoAn2EGki2UmB5q+Ca9yBvo9UsbtRFG =Piws -----END PGP SIGNATURE----- --FL5UXtIhxfXey3p5--
