Henkel 1126744 BONDERITE® M-CR 1000™ AERO Light Metals Conversion Coating - 5 Gallon Pail
Henkel BONDERITE M-CR 1000 (formerly Alodine 1000) is a clear conversion coating. As with the more common Alodine 1201, Alodine 1000 RTU, is also a registered trademark of Henkel Surface Technologies and is a chemical treatment process for aluminum used to provide corrosion protection and as a surface preparation for paint and adhesives. Sometimes called "aluminum passivation," it contains hexavalent chromium and is intended to provide corrosion prevention even when left unpainted.
Applications in which temperatures can reach over 120ºF can break down the corrosion resistance of the coating. In comparison to anodizing, this chemical film is more fragile and not generally recommended for high-use areas. This is a clear coating that leaves the surface with nearly the original aluminum appearance.
Alodine 1000 RTU methods and properties are defined by Mil-C-5541-F (Now AMS-C-5541 and AMS-A-2473). This product is listed on QPL-81706 and certified for Class 3 coatings.
