Designed with convenience in mind, the Henkel Bonderite M-CR 1132 Alodine Pen (formerly known as the Alodine 1132 Touch-N-Prep) is an ideal product for touch-up applications of dry-in-place military specification-approved chromate conversion coatings. This pen also reduces worker contact to chromating waste and solutions for improved safety and less mess.
Use the Alodine 1132 on metal surfaces as primer, to inhibit corrosion or for a decorative finish. Chromate conversion coatings may also help metals retain their electrical conductivity, making it a great choice for technical uses as well. The Bonderite M-CR 1132 (Touch-N-Prep Pen) is perfect for any small-scale touchup job on your aircraft. This useful pen can be used on a wide variety of other projects as well making it a great addition to any toolbox. The pen comes pre-filled with an alodine solution and the specialized applicator reduces the amount of contact between the pen material and the user. The Bonderite M-CR 1132 meets MIL-DTL-81706B, Class 1A & 3, Form VI and Method D specifications and is ideal for coating repair work.

This product is approved for Class 1A coatings in a wide range of coating weights. Heavy coating weights should be avoided for Class 3.
MIL-DTL-81706A describes a strip-and-weigh coating weight determination method. The following table offers some guidance in obtaining the proper coating weight range and estimates expected coverage area per pen (with a second coat applied over the first dry coat).
Light Coating Weight:
Class 1A and 3. Felt tip damp. Wet film appearance similar to a common felt-tipped type marker. Expected coating weight range is 13 – 18 mg/ft2. Dried appearance is nearly colorless. Expected coverage per pen is approximately 50 ft2.
Moderate Coating Weight:
Class 1A and 3. Felt tip moderately wet. Wet film appearance is heavy, but would not sag if held at a 90 degree angle. Expected coating weight range is 18 – 22 mg/ft2. Expected coverage per pen is approximately 35 ft2.
Heavy Coating Weight:
Class 1A ONLY. Felt tip very wet. Wet film appearance is very heavy and would sag and possibly drip if held at a 90 degree angle. Expected coating weight range is 22 – 35mg/ft2. Expected coverage per pen is approximately 25 ft2. If the coating puddles or tends to run, an excessive coating weight may be obtained. Be especially aware of depressions on the surface where excessive treatment solution could collect.
For economy and quality, the operator should be trained to keep the tip fairly moist- but not saturated with the treatment solution.
Proper Application and Use Procedure of ALODINE 1132 Touch-N-Prep Pen per MIL-DTL-81706, Class 1A and Class 3, Form VI, Method D for Aluminum and Aluminum Alloys Only.
