What is Iridite coating?
IRIDITE NCP® is an environmentally friendly chemical process that produces a protective conversion coating on aluminum and it’s alloys. The coating can be used as a finial finish or can also serve as a base for paints, high performance topcoats, powder coats, lacquers, or as a base for rubber bonding.
What does Iridite mean?
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 is RoHS and WEEE compliant. Application of the Iridite coating can be by dip, brush, swab, or spray.
Is Iridite the same as chromate?
Chromate means a “chromate conversion coating” which can be put on an amenable metal with the correct parameters for that metal. The chromate conversion coatings are sometimes referred to as “chem film” when on aluminum. Iridite is a proprietary name of a family of conversion coatings now owned by Macdermid.
Is Iridite RoHS compliant?
RoHS COMPLIANT IRIDITE AFT offers both traditional hexavalent Chemical Film and RoHS hex-free Chemical Film coatings.
Who makes Iridite?
MacDermid Enthone
Based on that deficiency, MacDermid Enthone developed the Iridite range of chromium-free coatings that has shown to be both safe and effective as a true replacement for the hexavalent chromium systems.
What is the difference between anodized and chem film?
The primary difference between Alodine (chem film) and anodizing is that anodizing is an electrolytic process and Alodine (chem film) is not. Alodine (chem film) and anodizing are both processes used in aluminum finishing to improve corrosion resistance. Both transform the outer layer of the surface of the metal.
What is the difference between Iridite and alodine?
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.
Is Iridite conductive?
Iridite NCP is a Trivalent chromium conversion coating that is mainly used as a pre paint coating for aluminium or as a corrosion resistant finish that still allows parts to be electrically conductive.
What is gold alodine?
Awlgrip Alodine 1201 Is A Chrome Conversion Coating for Aluminum. It Is A Non-flammable, Chromic Acid Based, Coating Chemical That Will Produce A Chrome Conversion Coating on Aluminum And Its Alloys. This Coating Is Gold to Tan In Color And It Becomes A Part of The Aluminum Surface.
Is clear chromate RoHS compliant?
Spectral offers RoHS compliant clear chromate finishes as per MIL-DTL-5541F. Our RoHS compliant chromate provide a conductive and corrosion protection film on aluminum. Common applications of chromating are electronic components, such as heatsinks and chassis requiring conductivity but oxidation protection.
What is alodine finish?
What is alodine finish? Alodine finish is a chemical conversion coating used for metals, particularly aluminum, to improve its resistance to rust and corrosion.
What is the thickness of anodizing?
Anodizing typically ranges up to 5 mils thickness. The three most common variations of aluminum anodizing include chromic anodizing (type I), sulfuric anodizing (type II) and hard anodizing (type III).
Is Iridite NCP conductive?
Iridite NCP offers a good level of electrical conductivity which is comparable to conventional chromate coatings and is often used on applications involving Electrical grounding.
Is yellow dichromate RoHS compliant?
This passivate does not produce the same yellow appearance, but it is RoHS compliant and offers high salt spray performance.
Is black chromate RoHS compliant?
metrics and specifications While this chromate conversion coating is still prevalent, the zinc plating industry has seen a rise in the need for trivalent black, as it is RoHS Compliant and more environmentally friendly.
What is the difference between Iridite and Alodine?
What is Type 3 anodize?
Type III Anodize finishes, also known as hardcoat finishes, are exceptionally hard and durable, qualities which allow them to resist damage due to corrosion and abrasion. Their greater material hardness and thicker oxide layers make them well-suited for applications that require excellent engineering characteristics.
What is the 720 rule for anodizing?
It is known that 720 amp-minutes of current per square foot of load are required to produce one mil (0.001″ or 25.4 microns) of anodic oxide (Westre 1997, 2017) (Westre 2000).
How do you apply Alocrom 1200?
Brush Alocrom mixture should always be applied quickly, liberally and evenly working upwards on vertical surfaces. Do not attempt to treat very large areas at one time. A nylon brush is normally effective; other soft bristle or sponges can be used for specific purposes.
