ABSTRACT:
A corrosion-resistant radio-frequency coaxial cable includes an inner conductor, a layer of dielectric material surrounding the inner conductor and an outer conductor comprising a laminate surrounded by at least one braided aluminum wire sheath. The laminate includes at least one layer of aluminum foil bonded to a substrate, where substrate is longitudinally wrapped about the dielectric material. A jacket of weather-proofing material surrounds the braided sheath. A corrosion-inhibiting coating is applied to the aluminum foil of the laminate, which coating is formed of a wax acid polyester. The wax acid polyester includes the compounds of a polybasic acid or anhydride, a polyol, and an effective amount of a lanolin wax acid to form a wax polyester in situ coating. The wax acid polyester is formed by the in-situ reaction of an aqueous emulsion of a polybasic acid or anhydride, a polyol and an effective amount of a lanolin wax acid.
