White Chromatizing
- White chromatizing is a chemical surface treatment process used to enhance the corrosion resistance of metals, particularly zinc and its alloys. It creates a passive, protective layer that improves the metal\'s durability while providing a clean, bright, and decorative finish. Unlike traditional yellow or colored chromate coatings, white chromatizing results in a colorless or slightly bluish appearance.
* Key Features of White Chromatizing:
1. Corrosion Resistance: Offers moderate to high resistance to corrosion depending on the formulation and application.
E2. co-Friendly Options: Modern white chromate formulations are often trivalent-chromium-based (Cr3+) to comply with environmental regulations like RoHS and REACH, which restrict the use of hexavalent chromium (Cr6+).
3. Decorative Finish: Produces a uniform, bright, and aesthetic surface ideal for parts that are visible or require a clean appearance.
4 Adhesion Promotion: Improves paint or coating adhesion when used as a pretreatment. # White Chromatizing Chemical Manufacturer.
