ACF-50 chemically treats metal using advanced polar bonding technology. It forms a hydrophobic film as it removes moisture from the metal surface. ACF-50 contains no water and is approved for electrical switches and connectors. ACF-50 has a strong capillary action so will creep into all the areas that moisture can; actively pushing out moisture and replacing it with protection. Where corrosion is already evident, ACF-50 will help inhibit further progress by insulating and electrically 'switching off' the corrosion cell.
