Chemical Conversion Coating/Plating

Ultra Seal offers Iridite-NCP, Black Oxide, and
Electrodeposited Tin 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 are available.

Black Oxide

This is a conversion coating formed by a chemical reaction producing a black iron oxide or magnetite on the surface of iron and non-stainless steels. No metal is added or removed from the part in this process therefore there are no dimensional changes to the part itself. It is used to add mild corrosion resistance, enhance appearance, and to minimize light reflection. Our process includes a post treatment of oil to help increase the protective properties of the black oxide coating.

  • Process forms a durable, non-dimensional black magnetite finish on all iron and non-stainless steels
  • ROHS Compliant
  • Tank Size – 48” L x 28” W x 48” D – Capacity – 44”L x 22”W x 42” D
  • $70.00 Minimum Charge / $0.40 per pound
  • Turnaround time: 3 – 5 Business days. Expedited services are available.

Electrodeposited Tin 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. Can be applied as a bright finish or matte finish.

  • Can be applied to Ferrous and Non-Ferrous Alloys
  • Bright or Matte Finishes
  • Rack and Barrel capabilities
  • Alkaline and Acid Chemistries available
  • Turnaround time: 5 – 7 Business days. Expedited services are available.
