In the past I have used a compound called NO-OX. Developed by Bell Labs for use on their power systems busses. Looks bad, smells like 2 week old catfish - but works like a champ. It's a highly conductive compound that doesn't corrode the parent metal or migrate at (reasonably) elevated temperatures.
Used to be sold through Greybar Electric. /mt -----Original Message----- From: Scott Lacey [ mailto:sco...@world.std.com] Sent: Wednesday, February 05, 2003 3:08 PM To: emc-p...@majordomo.ieee.org Subject: Maintaining conductivity of freshly machined aluminum To the group, Does anyone know of any conductive coating, preferably spray-on, that could be used on mating aluminum chassis surfaces? We manufacture (in very low volume) test equipment that is housed in a commercially manufactured anodized aluminum enclosure. Our machine shop mills the anodizing from mating surfaces and adds additional screw holes to improve bonding. The concern is that the surfaces will not remain conductive over time. Conventional dip alodyne is out of the question. The process would mar the black anodized finish on the exposed portions. We are considering using a wipe-on alodyne that Dupont sells to the autobody trade but have concerns as to its suitability for this application. The ideal would be a spray-on conductive coating that we could apply to the exposed aluminum after masking the anodized parts. We would abrade the surfaces with fine Scotch Brite just pryor to painting. Does anyone know of such a product?
