Abstract

Monsanto's flame retardant nylon M-340FR possesses physical and dielectric properties useful for making molded connector housings. However, it has been observed that gold plated copper contacts which are force fitted into these housings have a tendency to corrode through interaction with chemicals in the nylon, presumably the chemicals which make the nylon flame retardant. It has been observed further, that such corrosion may be eliminated by precoating the gold plated contacts with electrically approved lubricant composed of 20% polyphenylether (Monsanto OS124) and 80% inhibited 1,1,1 trichloroethane. Alternatively, the lubricant may be applied to the housing surfaces before inserting the contacts.
