Chemical Conversion Coating/Plating
Ultra Seal offers Iridite-NCP and Electrodeposited Tin Barrel Plating


Iridite-NCP
This is an environmentally safe, CHROME-FREE passivation treatment designed specifically for aluminum alloys. It applies a highly corrosion resistant conversion coating ideally suited to be painted or left as a stand alone corrosion resistant barrier.
- Non hexavalent chromium conversion coating
- Chemical conversion coatings are intended to provide corrosion prevention on unpainted aluminum items
- Improves adhesion of paint finish systems on aluminum
- Parts retain electrical conductivity
- Outperforms chromate coatings
- Coating color is clear to light blue
- Specifications: MIL DTL 5541F TYPE II, CLASS 3
- Turnaround time: 5–7 business days (expedited services available)
Electrodeposited Tin Barrel Plating
This process uses electrical current to deposit a thin layer of metal on the part. This silvery-white layer of tin is not easily oxidized in air, has good conductivity and corrosion resistance. It can be applied as a matte finish.
- Suitable for non-ferrous alloys
- Matte finish available
- Barrel plating process
- Acid-based chemistry
- Turnaround time: 5–7 business days (expedited services available)
