Zinc – High Build (Iridescent/Thick Film)

High-Build Zinc Passivation for Maximum Durability without Hex-Chrome

High-build (or Thick Film) passivation is a modern, Cr3+ (Trivalent) compliant finish designed to replace traditional hexavalent coatings. It provides a significantly thicker protective layer for parts exposed to harsher conditions.

Key Performance Advantages

Superior Corrosion Barrier: Often exceeds 120+ hours of salt spray resistance.
Environmentally Compliant: Fully REACH and RoHS compliant, meeting modern environmental standards.
Self-Healing Properties: The thick film layer offers limited self-healing capabilities if the surface is lightly scratched.

Typical Applications

Under-chassis automotive parts and outdoor power-distribution hardware.
Industrial valves and fluid handling components.

Trusted by industry professionals for parts that cannot fail in the field.
