- Innovation in Black – Atotech offers black surface finishing products for all zinc and zinc alloy processes
Zinc and Zinc Alloy Electroplating – Functionality and Aesthetics
Tradition and Innovation
Zinc and zinc alloy coatings are usually deposited on ferrous substrates to enhance their bulk properties and protect them
from corrosion. Atotech provides suitable coating combinations for a wide range of applications and fulfills global automotive OEM requirements. Several post-treatments can be also combined in order to achieve different colors and higher corrosion resistance.
We have invested in the development of environmentally responsible technologies and can provide innovative solutions. For more information see our product news.
Zinc and Zinc Alloy Electroplating
| Type of Process | Product | Features |
| Acid Zinc | Zylite® | - High brightness - Ideally suited for plating of cast iron hardened steel surfaces and high volume production of small parts such as fasteners - Boric acid-free electrolytes (Zylite® ST processes) also available |
| Cyanide-free Alkaline Zinc | Protolux®, Unizinc NCZ | - Outstanding coating thickness distribution and throwing power - Well suited for plating complex shaped components |
| Zinc Nickel | Reflectalloy®, Zinni | - Enhanced corrosion protection, compared to other zinc coatings - Elevated hardness and high temperature resistance |
| Zinc Iron | Protedur®, Zinfer | - High ductility and thickness distribution - Excellent adhesion level of passivated coatings |
| Post-treatment | Passivates | Supplementary finishes such as Cr(VI)-free conversion coatings providing beneficial and essential characteristics to zinc or zinc alloy coatings |
| Sealer, Corrosil® | Final finish to improve appearance and overall corrosion performance of zinc and zinc alloy coatings |
