BONDERITE® 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 from a light iridescent golden to tan.

BONDERITE M products are used in the surface modification of metals and usually applied in a multi-stage process. The performance of these surface treatments depends on various factors such as the preceding cleaning or etching steps (BONDERITE C portfolio), line design or process parameters.
