MIL-DTL-5541 is the process specification for chemical conversion coatings on aluminum and aluminum alloys. This specification references the qualified products list (QPL) on MIL-DTL-81706, which lists both BONDERITE M-CR 1132 AERO and BONDERITE M-CR 871 AERO. Henkel certifies both products to MIL-DTL-81706B.
BONDERITE M-CR 1132 AERO is a hexavalent chrome chemical conversion coating and BONDERITE M-CR 871 AERO is a trivalent chrome chemical conversion coating. BONDERITE M-CR 1132 AERO leaves an apparent yellow gold coating after application and BONDERITE M-CR 871 AERO leaves a clear iridescent coating after application. Performance of both coatings meets the same corrosion protection and paint adhesion requirements per MIL-DTL-81706B.
