There is a product by Ideal called Noalox specifically for the application of preventing deterioration of aluminum connections, primarily for the electrical trades. It is an anti-oxidant joint compound for use on connectors and aluminum wire, a grey paste which does not appear to dry out. It is applied first to wires and then abraded with brush or emery cloth to remove oxide, followed by assembly. I assume the same process would work with you; add the compound, machine the anodizing through it, assemble the hardware and wipe away the excess. I got mine at Home Depot.
Bob Johnson ITE Safety From: [email protected] [mailto:[email protected]] On Behalf Of Scott Lacey Sent: Wednesday, February 05, 2003 5:08 PM To: [email protected] 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?
