Iridite is a trade name for a whole family of chromate conversion coatings. Alodine 1200S is the trade name for aluminum chromate that meets MIL-C-5541. Iridite 14-2 is the particular trade name for a product that is chromate conversion for aluminum.
What is clear Iridite finish?
Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum. Although the iridescent gold finish is very attractive, it is not as durable as an anodized finish. Two classes of coatings are available under Mil-C-5541 and Mil-C-81706.
How thick is Iridite coating?
Aluminum chromate conversion coatings, often referred to as chemical film or under the trade names Alodine or Irridite, produce a thin coating in the range of 0.00001-0.00004 inches in thickness.
How does chromate conversion coating work?
1 Chromate conversion coatings. Chromate conversion coatings are obtained by chemical reaction with the metal being treated, to form a complex chromate film over the entire surface. The coatings can be applied to aluminium, zinc, cadmium and magnesium.
What is Iridite coating?
Iridite is a N.C.P. (non-chrome chemical process) that produces a protective chromate conversion film coating on aluminium and its alloys. The process produces coatings in shades ranging from clear to dark yellow. The darker the shade of the final coating, the greater the corrosion protection provided to the metal.
What is Iridite NCP?
Iridite NCP is an innovative new process that offers extremely high resistance to corrosion, tested to 1000 hours on many aluminium alloys. For new chrome free technology that meets all environmental standards, bare corrosion resistance without painting, even after heating or baking.
Is Iridite coating conductive?
These are conductive of electricity and therefore useful in applications in electronic industries where the component needs to retain its electrical conductivity but also be protected against corrosion. In addition this conductivity means it is an excellent pre-treatment for painting and powder coating processes.
Can you Alocrom steel?
“Alodine” is a Henkel trade name for their line of chromate conversion coatings for aluminum and light metals. No, chromate conversion coating is not applicable to bare steel, although steel may be zinc plated and then have a chromate conversion coating applied.
Is Iridite conductive?
What is the meaning of Iridite?
: having or showing knowledge that is gained by studying : possessing or displaying erudition an erudite scholar.
What is gold Iridite?
2007. To add to what Ted said, Iridite is a trade name for a line of chromate conversion coatings. Yellow Iridite is sometimes used as a general name for yellow conversion coatings on a variety of substrates (zinc, cadmium, aluminum, etc).
Mil-C-5541F, Chemical Films, Chromate ” Iridite “, (Aluminum) Chemical Film coatings are gelatinous films which provide some sort of a barrier medium to retard corrosion on aluminum surfaces and enhance adhesion of subsequent coatings such as paints and primers. Color can vary from colorless to golden – iridescent – brown.
Can you use Iridite on aluminum?
Chromate (Iridite) on Aluminum Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum. Although the iridescent gold finish is very attractive, it is not as durable as an anodized finish. Two classes of coatings are available under Mil-C-5541 and Mil-C-81706.
What is the difference between iridite and Alodine?
Iridite is a proprietary name of a family of conversion coatings now owned by Macdermid. Alodine is similarly the proprietary name of a family of conversion coatings now owned by Henkel. The exact capabilities and uses of a specific Iridite or Alodine formulation is determined by the numbers that follow as in -14.
What is iridescent gold finish on aluminum?
Chromate (Iridite) on Aluminum Chromate (Iridite) on Aluminum Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum.
