No Tarn PM-3 Silver Antitarnish bath was specifically developed for protection of silver from sulphidation. It is based on aqueous, metal-free solution in which the organic inhibitor is present as a fine dispersion. The passivation layer is applied by immersion and is specifically designed for silver surfaces.
