Trivalent chromium-based chemical treatment film for zinc die casting - Chromating treatment
This treatment provides excellent corrosion resistance and improves the adhesion of the coating film.
Trivalent Chromium-Based Chemical Treatment Coating for Zinc Die Casting Chromating treatment generates a chemical coating on the surface of zinc die castings using trivalent chromium compounds, providing excellent corrosion resistance and improving the adhesion of the paint as a pre-treatment for coating. This treatment does not use harmful hexavalent chromium compounds, making it compliant with environmental regulations. 【Features】 - Does not contain hexavalent chromium compounds - Corrosion resistance → Comparable to hexavalent chromium coatings → Over 120 hours until white rust formation in salt spray test → 50 hours in salt spray test for ZDC1 (Type 1 zinc die casting material) - Ideal for painting and surface preparation - Coating contact resistance is below 0.8 mΩ/cm² - Generates a direct coating on the surface of zinc die castings - Minimal dimensional changes before and after treatment - Very cost-effective - Capable of mass production For more details, please contact us or refer to the catalog.
