A Beginner’s Guide to Iridite NCP

Dorsetware specialises in metal plating and electroplating, and one of the finishes it administers is iridite NCP plating and coating. The iridite NCP process produces a protective, corrosion-resistant coating on aluminium and its alloys. For this reason, it’s ideal to use as a standalone finish, but it is also favoured to use a base for paints, lacquers and high-performance topcoats as it provides a clean, adhesive surface.

What is the Iridite NCP process?

We use an environmentally friendly chemical process to provide an iridite plating and coating on customer products.

  • De-grease and water-wash the product
  • Removal of any oxidisation
  • Wash the product with water
  • Water rinse again
  • Add the iridite NCP
  • Wash with purified water

What are the uses?

  • Iridite NCP can be used as a final finish
  • Base for high-performance topcoats, paints, lacquers, powder-coats or rubber bonding


  • Iridite NCP is corrosion resistant, unlike most non-chrome conversion coatings
  • Superb paint adhesion
  • Iridite NCP doesn’t contain lead, cadmium, chromium, mercury or PBB/PBDE compounds, meeting ELV, RoHS and WEEE standards
