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 aluminium and its alloys. This coating exhibits bare, unpainted, corrosion resistance that is equal to hexavalent chromates on many aluminium alloys. The coating can be used as a final finish and can also serve as a base for paints, high performance topcoats, powder paints, lacquers, or as a base for rubber bonding.

Features

Provides an excellent primer or paint base, or for other subsequent organic treatments when tested in accordance with ASTM D 3359.

Tank size for Iridite is 1200 x 600mm.

A concentrated liquid trivalent chromium based chemical which when diluted with water
will form an iridescent blue to tan protective chromate coating of 50 – 500 mg/m2 on clean, oxide-free aluminium and aluminium alloy surfaces. It is approved for aerospace to U.S. MIL-DTL-81706 and MIL-DTL-5541F

Excellent corrosion protection with or without paint.
Excellent paint or powder adhesion allowing metal deformation after painting.
The coating has low electrical resistance - under 0.8 milli-ohms/cm2.

Tank size for SurTec is 1200 x 600mm.
