Henkel Bonderite M-CR 1132 M AERO Touch-N-Prep Conversion Coating – 5g Mini Pen for Aerospace Spot Repair

Henkel Bonderite M-CR 1132 M AERO Touch-N-Prep is a convenient pen-format chromate conversion coating product for aerospace aluminum surfaces — providing spot repair of bare metal areas, scribe marks, and paint damage zones where the conversion coating layer has been disrupted, restoring both corrosion protection and paint adhesion without the need for mixing, spray equipment, or brush application tools. The pen format is a breakthrough in conversion coating application convenience for line maintenance and hangar operations where portability and ease of use are critical for rapid repair turnaround.

Chromate conversion coating (chemical film) is a critical step in the aerospace corrosion protection system — the conversion coating layer provides active corrosion inhibition through chromate ion release and a chemically bonded interface between the aluminum substrate and the primer coat above. Without conversion coating, bare aluminum surfaces have dramatically reduced corrosion resistance and paint adhesion durability, leading to accelerated corrosion and paint peeling at repair areas.

The 5g mini pen provides a practical single-use or short-term supply of Touch-N-Prep conversion coating for individual technicians performing spot repair operations — with the pen format enabling precise application to specific bare metal areas without overcoating surrounding painted surfaces.

Technical Information

Bonderite M-CR 1132 M AERO uses chromate-based chemistry to produce a chromate conversion coating on aerospace aluminum alloy surfaces. The hexavalent chromate ions in the solution react with the aluminum oxide surface to form a thin, adherent chromate-aluminum oxide conversion layer that provides active corrosion inhibition — the chromate reservoir in the coating layer releases inhibiting ions in the presence of moisture, passivating any anodic sites on the aluminum surface that would otherwise initiate corrosion.

The Touch-N-Prep pen delivery system eliminates the traditional two-part mixing, surface wet time management, and rinse water requirements of conventional chromate conversion coating application, making it practical for spot repair by individual maintenance technicians at the aircraft without establishing a dedicated chemical processing area. The pen tip applies the conversion coating solution directly to the bare metal area with controlled, minimal overspray.

After application and the required contact time, the conversion coating surface is ready for priming per the applicable aircraft maintenance procedure. Verify the applicable Boeing, Airbus, or military SRM/AMM for the specific Touch-N-Prep application procedure, required wet time, and priming requirements before use on certified aircraft.

Frequently Asked Questions

Q: What is Bonderite M-CR 1132 M AERO Touch-N-Prep?
A: It is a pen-format chromate conversion coating for aerospace aluminum spot repair — restoring corrosion protection and paint adhesion at bare metal areas without mixing or spray equipment.

Q: MPN for Bonderite M-CR 1132 5g pen?
A: MPN is 2968637.

Q: Why is conversion coating needed before priming?
A: Conversion coating (chemical film) provides active corrosion inhibition and a chemically bonded surface for primer adhesion on bare aluminum. Without it, primer adhesion durability and corrosion protection are significantly reduced.

Q: Does the Touch-N-Prep pen need rinsing after application?
A: Traditional conversion coating requires water rinsing. The Touch-N-Prep pen format simplifies the process — consult the Henkel TDS and applicable aircraft maintenance manual for the specific rinse or no-rinse procedure for your application.

Q: Is Bonderite M-CR 1132 approved for aircraft use?
A: M-CR 1132 M AERO is part of Henkel’s AERO aerospace-qualified product line. Verify the applicable aircraft SRM or AMM for approval of Touch-N-Prep use on your specific aircraft type and repair category.
