Chemical Conversion Coatings

Chemical conversion coatings are coatings that provide a superficial layer between the metal compound and the coating. Unlike other coatings, chemical conversion coatings use electrochemical or chemical reactions to achieve their coating layer, making their application a unique and effective process that stands alone in its industry. Chemical conversion coatings offer economical corrosion protection and produce a surface that's already prepared for powder coats and paint. When you choose chemical conversion coatings, you're preserving electrical conductivity as well as the integrity of your components.

At Advanced Coating Technology, we provide chemical conversion coating services to protect your components from corrosion and the elements. Chemical conversion coating is perfect for metal components made from aluminum, cadmium, copper, magnesium, silver, steel, tin and titanium.

Benefits of Chemical Conversion Coatings

Chemical conversion coatings help your components achieve greater corrosion resistance while preserving their electrical conductivity. Unlike anodizing, chemical conversion coatings don't require electricity in their coating process, making them a more cost-effective choice. Chemical conversion coating is also preferable for its aesthetics, as it can produce a clear or colored coating depending on the surface and your preference.

The advantages of chemical conversion coatings make them useful for everyday items such as tools and complicated equipment. Chemical conversion allows for quick processing times, and the process itself is very environmentally friendly. With chemical conversion coatings, you can improve the adherence of adhesives and paints while protecting your product from abrasion and chemical interference. 

Applying Chemical Conversion Coating

At Advanced Coating Technology, we completely clean and prepare all components and equipment before applying conversion coatings. This cleaning process may include washing and decontaminating the substrate and mechanical cleaning via blasting or abrasion. We then apply conversion coatings on the metal parts of your components. These acidic coatings transform the metal substrate to an iron or zinc phosphate surface that improves paint adhesion and field performance. 

After the acidic coating has transformed the metal substrate, it may undergo one of the following processes depending on the desired outcome:

  • Anodizing: A process used for chemically converting aluminum surfaces.
  • Chromate conversion: Another process for aluminum conversion that creates a shiny coating.
  • Zinc and iron phosphate conversion: A method developed for transforming steel substrates.


After the chemical conversion is complete, you'll have a surface ready for painting and curing. Chemical conversion allows the paint to bond mechanically to components, ensuring it won't flake off steel surfaces or undergo delamination. Properly prepared chemical conversion coatings create thin crystal films that provide an excellent base for paints and adhesives to attach to the substrate.
