Thin Film Conversion Coatings

Commonly known as Alodine or Passivation, our fully automated PLC controlled overhead-hoist lines process a variety of thin film conversion coatings for aluminum substrates. Our current Chrome-Free and Trivalent Chrome chemistries include Bonderite M-NT 5200, M-NT 5900, and M-NT 2040. These coatings are typically used to promote adhesion and / or weldability on aluminum, most commonly on leading electric vehicle platforms.

We have some of the largest tanks in the nation.  Because of this, we can process large, heavy parts or many small delicate parts with the same ease and efficiency.

Our thin film conversion and anodizing tanks are some of the largest in the nation.


We work with top certified suppliers, and commonly work with a variety of chemistries to meet our customer needs. If the chemistry isn’t listed to the left (i.e. BASF Gardobond as an example), it doesn’t mean we can’t offer it upon request.
