The gold or yellow color is the inherent color of hexavalent chromium so, traditionally, the yellow color implied more chrome and more corrosion protection. In these days of RoHS, most chromate conversion coating is actually trivalent, and any yellow color is just
Both Alodine and Andodize are chemical processes used to create a protective oxide barrier on certain types of metal. This barrier, when applied to metals such as aluminum, niobium, tantalum, titanium, tungsten and zirconium protects the metals from corrosion. The difference between Alodine and Anodize lies mostly in the process of applying or

It is often referred to by its trademarked names Alodine Iridite coating, or Yellow Iridite Specifically the chemical conversion coating when used in the above processes is a
Alodine Vs. Anodizing Alodining is a process in which a metal is coated with a chemical called alodine. This coating hardens to the surface and can last for years if painted, not requiring reapplication. Anodization. Anodizing is the process of laying a metal in a solution of salts and running a current through it. This attracts metals from
M-CR 1200S AERO (ALODINE 1200S) is a brown, metal pre-treatment powdered chemical used to produce a protective coating on aluminum which minimizes corrosion and provides an improved bond for paint. Surfaces treated with it range in color

1132 will produce the traditional coating color on aluminum alloys. Alodine 5200 5700 Alodine 5200 produces a clear, chromate-free conversion coating. Alodine 5200 is considered environmentally friendly and thus exhibits lower toxicity than the chromate
Product Description Alodine (FAD0003) will no longer be sold or distributed by Endura due to health and environmental concerns of the product. This is in line with Endura ongoing commitment to Health Safety and Environmental issues. MetaLink is recommended in cases where a product is required to provide a pre-bond adhesion promotion of the
1132 Touch-N-Prep pen TNP pen conquers Aerospace Market After Boeing-St. Louis has implemented a new method to apply chemical conversion coatings on aluminum and aluminum alloys by involving the use of an applicator pen called Touch-N-Prep Alodine 1132, also Europe has now discovered the many advantages of this application
Chromate Conversion Coating (also commonly referred to as Chemical Film, Chem Film, Alodine or Iridite) converts the surface properties of the substrate (typically aluminum or magnesium) as compared to plating which applies a coating onto the surface of the substrate. Chromate provides excellent corrosion resistance,
