Trivalent Chrome Passivation is an environmentally friendly post-treatment process applied to zinc-plated components to provide excellent corrosion resistance and long-lasting surface protection. It forms a thin, durable chromium (Cr³⁺) conversion coating that enhances the performance of the zinc deposit while maintaining an attractive, uniform finish. Unlike traditional hexavalent coatings, trivalent passivation complies with modern environmental regulations such as RoHS and ELV, making it a preferred choice for sustainable manufacturing.

Widely used in the automotive, electrical, electronics, engineering, fastener, and hardware industries, Trivalent Chrome Passivation offers excellent adhesion, improved wear resistance, and superior protection against moisture, oxidation, and white rust. Available in Clear, Irredescent Yelllow, Blue, Black, and Thick Film finishes, it ensures consistent coating quality, enhanced durability, and reliable performance for components exposed to demanding industrial and outdoor environments.
