New Henkel repair pen enhances efficiency in confined aircraft areas with superior corrosion protection

Henkel has introduced the Bonderite M-CR 1132 M AERO Pen to simplify touch-ups in hard-to-reach areas like fastener holes.

(IN BRIEF) Henkel Adhesive Technologies has released the compact Bonderite M-CR 1132 M AERO Pen, designed to make aircraft surface repairs in confined areas such as small fastener holes more efficient and precise. As a smaller version of the original Touch N Prep Pen, the tool delivers controlled application of dry-in-place chromate conversion coating that can either air dry or be force dried with warm air. The pen’s streamlined design reduces material waste, labor time, and operator exposure, while an optional slim tip attachment allows penetration into holes as small as 3/16 inch. With its no-rinse formula, the new solution provides excellent corrosion resistance for aluminum surfaces, supporting safer and more effective maintenance operations.

(PRESS RELEASE) DÜSSELDORF, 16-Sep-2025 — /EuropaWire/ — Henkel Adhesive Technologies has expanded its line of aircraft surface treatment solutions with the introduction of the Bonderite M-CR 1132 M AERO Pen, a compact tool engineered to simplify touch-ups in challenging areas such as fastener holes. As a global leader in structural adhesives and surface treatments for both aircraft OEM and MRO sectors, Henkel continues to refine solutions that enhance precision and efficiency in maintenance operations.

The new pen is a smaller, more convenient version of the established Bonderite M-CR 1132 AERO Touch N Prep Pen. It applies a dry-in-place chromate conversion coating with a controlled flow, enabling consistent coverage across aluminum surfaces. The coating can either air dry or be accelerated using warm air, giving technicians greater flexibility during the repair process.

Engineered with ease of use in mind, the design significantly reduces waste, lowers application time, and helps limit operator exposure to chromating solutions, thereby improving overall safety and efficiency. For situations requiring even more precision, an optional extended slim tip is available, making it possible to accurately treat tight areas, including fastener holes as small as 3/16 inch.

Thanks to its no-rinse formula, the Bonderite M-CR 1132 M AERO Pen ensures reliable protection against corrosion while maintaining high performance standards. This innovation provides aircraft maintenance professionals with a practical, highly targeted solution for repairs that demand accuracy in confined areas.
