Hexavalent Chrome Passivation is a highly effective post-treatment process applied to zinc-plated components to enhance corrosion resistance and extend service life. It forms a protective chromate conversion coating that provides excellent resistance against rust, moisture, and harsh environmental conditions while improving the durability of the zinc deposit. Available in finishes such as Iridescent (Yellow), Blue, Black, and Olive Green, hexavalent passivation also enhances the appearance of metal components with a uniform and attractive finish.
Widely used in the automotive, electrical, engineering, fastener, and hardware industries, Hexavalent Chrome Passivation offers excellent adhesion, self-healing properties, and reliable long-term protection for components exposed to demanding operating environments. It is suitable for a wide range of zinc-plated steel parts where high corrosion performance and consistent surface quality are essential.
