Iridite 14-2 is a chemical process that produces a protective chromate conversion film on aluminum
and aluminum alloys. Application is by dip, brush, swab, or spray, producing coatings ranging from
clear to dark yellow. The darker coatings providing the greatest corrosion protection. The coating can
be used as a final finish or can be dyed various colors. It can also serve as a base for paints and high
performance top coats, lacquers, or as a base for rubber bonding.
The operating range of Iridite 14-2 is extremely flexible. Suitable adjustments of the
Iridite 14-2 concentration can accommodate wide variations in immersion time, the corrosion
protection (film thickness) desired, and the alloy to be treated
Features :
- Coating has minimum effect on electrical characteristics of aluminum for high or low frequency
work when used at lower concentrations
- Coating protects abraded anodized surfaces and also provides electrical contact to those surfaces
- Coated aluminum surface can be welded by shielded arc method or by spot welding
- Bath activators are self-regulating, providing maximum uniformity of results and ease of control
- Qualified under Specification MIL-DTL-81706B, Class 1A, Form II, Method A, B, C; and under
Class 3, Form II, Method C. The clear Iridite 14-2 finish also qualifies under Class 3, Form II,
Method C of the same specification. (Specification MIL-DTL-81706B qualifies products for use in
conforming to Specification MIL-C-5541E)
