CHROMATE CONVERSION

Chromate conversion treatments play an essential role in the metal finishing industry. In the chromate conversion process, the surface metal reacts with chromium compounds and becomes a component of the chemical film that is produced. This reaction creates a soft, gel-like film that hardens over time and becomes more resistant to abrasion and handling.

Chromate films are available in different colors, with colorless clear coatings and iridescent yellow coatings being the most common. Typically, a darker colored film will provide greater corrosion protection. Chromate films improve corrosion resistance, enhance decorative appearance, and increase adhesion of paint, lacquer, and other organic finishes.
