Technical Information
Henkel BONDERITE M-CR 120 AERO (formerly Alodine 1200S) is a chromate conversion coating concentrate used to produce a protective chemical film on aluminum, magnesium, zinc, and other light metal alloy surfaces. The chromate conversion process produces a thin, corrosion-resistant, conductive film directly on the metal surface by chemical reaction — no electrical current required. The gallon can format provides concentrate for diluting into working solution for brush, spray, or immersion application. BONDERITE M-CR 120 AERO meets MIL-DTL-81706 and MIL-C-5541 specifications and is widely used in aerospace manufacturing, MRO, and military equipment maintenance for both corrosion protection and primer adhesion promotion.
