Alkaline Zinc Coating

Zinc coating is one of the most widely used surface treatment methods in metal coating processes to provide protection against corrosion. Alkaline zinc coating processes, in particular, are widely used in automotive, fasteners, and general industry applications due to their ability to ensure homogeneous coating distribution and high surface quality.

With passivation and topcoat (sealer) systems applied after electrolytic zinc plating, corrosion resistance is significantly increased, while aesthetic appearance and functional properties are also improved. Thanks to Cr+3 and Cr+6 passivation alternatives, different performance levels can be achieved depending on application requirements.

As Erkap Industrial Coating Solutions, we provide high-performance and sustainable metal coating solutions tailored to customer specifications by offering alkaline zinc coating, passivation, and topcoat processes in an integrated manner.
