Zinc-Alkaline

Zinc alkaline coating is a reliable solution for the anti-corrosion protection of metal parts, especially in the automotive and component industries.
This process is carried out by electrodeposition in alkaline baths, achieving a uniform layer of zinc that acts as a barrier and cathodic protection against corrosion.


Thickness

The typical coating thickness ranges from 5 to 25 μm, depending on the application and customer specifications.

Chemical Composition

  • Layer of pure metallic zinc electrolytically deposited on the surface of the steel.
  • The alkaline bath contains complexing agents and additives that ensure homogeneous distribution and excellent coverage.

Main Features

  • Look: Glossy or semi-glossy finish, ideal for decorative and functional applications.
  • Adherence: Excellent adhesion to steel and machined parts.
  • Corrosion protection: It acts as an anode to steel, offering galvanic protection and superior resistance in aggressive environments.
  • Chemical resistance: Good tolerance to humid and polluted environments.
  • Compatibility: It can receive additional passivation (white, blue, black) to improve corrosion resistance and aesthetics.
