Did you know there’s a cleaner, easy-to-use method of repairing conversion coatings on aircraft and aircraft part surfaces?

Henkel’s BONDERITE M-CR 871 AERO (also known as Alodine 871) and BONDERITE M-CR 1132 AERO (also known as Alodine 1132) coating pens feature their convenient Touch-N-Prep applicator and unique non-rinsing technology that effectively protects and repairs bare aluminum substrates to prevent corrosion. Both Alodine 871 and Alodine 1132 are dry-in-place coatings that don’t require rinsing and can be air-dried or force-dried with hot air or infra-red lamp.

The Touch-N-Prep ready-to-use pen applicator provides an easy and safe application method for touch-ups by delivering the coating directly onto the surface. It features a high-density acrylic tip that can be modified with a single-edge razor blade to form any shape or used with specially designed replacement slim tips available for purchase.

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.
