Alkaline Non-Cyanide

E-Brite Ultra-Alk — Alkaline Non-Cyanide Zinc Plating

E-Brite Ultra-Alk is a thoroughly tested, stable and production proven zinc plating brightener process. It is suitable for either rack or barrel plating. E-Brite Ultra-Alk provides better zinc metal distribution than traditional alkaline zinc or chloride zinc plating systems. Operating parameters are wide and therefore it is an easy process to maintain.

E-Brite Ultra-Alk deposits are ultra bright and ductile over a wide current density range. It plates mirror bright to 120 ASF. The deposits readily accept all chromate conversion coatings. The process was developed to replace cyanide zinc plating without sacrificing the quality of the zinc deposit. Waste treatment is simplified and requires only a simple pH adjustment to precipitate zinc metal as zinc hydroxide.

Benefits of Zinc Plating:

• Ultra bright zinc deposit. Approaching that of chloride zinc.
• Excellent ductility & adhesion. Maintains ductility even with thicknesses in excess of one mil.
• A low stress deposit.
• Superior zinc deposit plate distribution.
• Consistent distribution.
• Excellent chromate conversion coating receptivity.
• Zinc deposit appearance is comparable to cyanide or chloride zinc.
• Operates within wide range of bath chemistry.
• Temperature tolerance up to 120˚F, which reduces cooling costs.
• Excellent brightener stability and brightener life of 30,000 amp hours.
• Suitable for either rack or barrel plating.
• Simple waste treatment procedure.
• A reliable, easy to maintain process.
• It contains no complexers or chelating agents.
• It accepts all hexavalent and trivalent chromates.
