What is the difference between zinc coated and Gold Coat connectors?
Zinc Zinc provides galvanic protection in the form of a “sacrificial metal”. This type of protection occurs because zinc is a more reactive metal than the underlying protected metal. Zinc is applied to steel through the “galvanizing” process. Gold Coat This type of barrier protection is provided from an organic coating. Types of organic coatings include resins, plastics, paints, enamels, and oils. The protective coating is an inert material that provides a physical barrier between the base metal and its surrounding environment. With this barrier in place, the metal will not react chemically and produce corrosion products. The metal cannot release electrons because the electrons cannot freely react to their environment.
