Chemical Film Specifications (Non-RoHS) & (RoHS) Plating:
The IRIDITE NCP, Non-Chrome Passivate has been developed in response to the ELV, RoHS and WEEE directives. The IRIDITE NCP does not contain Lead, Cadmium, Chromium (hexavalent or trivalent), Mercury or PBB / PBDE compounds.

IRIDITE NCP is an environmentally friendly chemical process that produces a protective conversion coating on aluminum and its alloys. The coating can be used as a final finish or can also serve as a base for paints, high performance topcoats, powder coat, lacquers, or as a base for rubber bonding.

Features:

  • Elimination of the use of hazardous hexavalent and trivalent chromium.
  • Provides corrosion protection that rivals conventional chromate conversion coatings when tested in accordance with ASTM B 117.
  • The conversion coating passes the requirement of Mil-DTL-5541 Type II Class 3 and Mil-DTL-81706.
  • Wide operating range for time, temperature and concentration.
  • Provides excellent primer or paint base, or for other subsequent organic treatments when tested in accordance with ASTM D 3359.
  • No aging or curing required before topcoat application.
  • Baking of treated parts does not affect the coating as with traditional yellow chromates.
  • Rinsing the IRIDITE NCP coated aluminum in hot water does not compromise the corrosion resistance of the coating.
  • Reduced waste treatment costs when compared to chromates.
