These days with regulations favoring the use of non-hexavalent chrome conversion coatings, Iridite® NCP and Alodine® 5200 are aluminum conversion coating products that are free from hex chrome.

Imdite NCP是为了适应ELV，ROHS和WEEE的要求而研发的一种无铬钝化工艺。 IRIDITE NCP不含铅、镉、铬（六价和三价）、汞和PBB/PBDF，它是一种用於铝和铝合金表面膜层处理的环保型流程，它形成的膜层可作为最终的表面层，也可以作为油漆、粉末涂布、高性能涂层的底层，同时可作为表面粘合橡胶的底基。 IRIDITE NCP制程包含IRIDITE NCP START（110561）和IRIDITE NCP Replsenisher (110544)。 IRIDITE NCP START用於建浴，不需做其他任何添加剂便可得 …

Chromate conversion coatings are commonly applied to items such as screws, hardware and tools. They usually impart a distinctively iridescent, greenish-yellow color to otherwise white or gray metals. The coating has a complex composition including chromium salts, and a …

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.

IRIDITE™ NCP is a chrome-free, zirconium-based conversion coating. It 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.

IRIDITE TCP™ System is a transparent passivation for aluminum based on Chrome-III compounds. It can be applied as post-treatment for pure, alloyed, and cast aluminum and produces a colorless to slightly iridescent protective film.

Chromate conversion coatings on aluminum are also known as yellow Bonderite, Iridite, and Alodine, or Chem Film. They are used for everyday aluminum components, hardware, automotive wheels, heat sinks and aerospace applications (aircraft hulls, side and torsion struts, shock absorbers, flight control systems, and landing gear).

Iridite, primarily used for treating aluminum surfaces, is a significant surface coating process employed in diverse industries, including aerospace and electronics. The Iridite process involves preparing the aluminum substrate by cleaning it thoroughly and then applying a conversion coating free of hexavalent chromium.

Also known as iridite coating, chemfilm creates a protective layer on the outside of an aluminum part. But it also serves the purpose of providing a base layer for painting, and provides good corrosion protection.

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.
