Chromate Conversion Coating

The chromate conversion process is a simple yet well-established process in our plating business. This versatile coating is popular among customers for a multitude of reasons.

The process is primarily used to improve the corrosion resistance of the coated item, or as an undercoat for paint application. We can offer clear and yellow-colored chromate coatings based on our customer’s requirements.
