A conversion coating is a chemical treatment applied to manufactured parts that superficially converts the material into a thin coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion, improve adherence of other coatings, lubrication, or decoration.
Our chromate conversion coating for aluminum involves the following steps:
- Degreasing and rinsing to remove oil, grease, oxides, and heavy metallic impurities
