Frequently Asked Questions

AUTODEPOSITION is a patented, waterborne, organic coating process using chemical rather than electrical energy to coat metal parts with a functional and uniform coating.

"AQUENCE® is a registered trade name for coating products supplied by Henkel." (ACC ® is also a registered trademark)

The thickness of the coating is time and temperature dependent. The coating itself becomes "self-limiting" as the reaction slows with the thickness of the film. That is why autodeposition creates a uniform coating, even in hidden or recessed areas. The final result provides a functional coating that is tough and resistant to aggressive environments.

The following is a list of automotive OEM approvals for Aquence® Coatings:

For 30 years, the brand for autodeposition coatings has been known as "Autophoretic".  At the strong demands of the automotive customers and markets, Henkel has made significant investments for the last two years in the autodeposition coating technology in order to develop new products which will expand the performance and substrate use. For this reason, and with the launch of new coatings for the automotive and ACE frame and chassis applications, Henkel decided to re-launch the technology into the new markets with a new brand; "AQUENCE".  The name "AQUENCE is the combination of the words "AQUA" and "SEQUENCE" reflects the intentions by Henkel to provide a water-based environmentally responsible coating (AQUA) and that it will belong to an simple and efficient application process (SEQUENCE).
Henkel announced the new brand in February of 2008 and will gradually move all autodeposition products under this new and exciting brand image.
