M-CR Magnesium Aero Conversion Coating
8 oz Kit
Description
Chromate conversion coating for magnesium alloys – a corrosion protection and adhesion-enhancing coating.
The Ultimate Guide to Henkel/Loctite Conversion Coatings for Aerospace and Industrial Maintenance
What are Conversion Coatings?
Conversion coatings are an important surface treatment for aerospace and industrial maintenance, increasing corrosion resistance and promoting paint adhesion on common metal substrates, particularly aluminum and magnesium alloys.
These coatings undergo a chemical reaction with the metal surface to form a protective layer that not only prevents corrosion but also improves bonding strength for coatings and adhesives. Henkel/Loctite is the conversion coatings manufacturer you have come to know and respect over the years, and Greenwood Aerospace is your trusted source for their products.
Why Choose Henkel/Loctite Conversion Coatings?
Henkel Chemicals is a well-known brand that has been around for a long while and owns other common household brands, namely Loctite, which every mechanic worth their salt owns a good stock of.
Henkel produces conversion coatings widely used in aviation and aerospace that meet rigorous military and industry standards, including MIL-DTL-81706 and MIL-DTL-5541. Their products offer superior performance in corrosion prevention and paint adhesion, making them ideal for use in military aircraft maintenance tasks on the airframe.
Let’s take a look at these four products and see how they can work.
Product 1: M-CR Magnesium Aero Conversion Coating Chromate (8 oz Kit)
M-CR Madnesium Aero Conversion is a chromate-based conversion coating that is designed for use with magnesium alloys.
Key Features
- Non-flammable aqueous solution with chromic acid as the active ingredient.
- Produces a hard, brown-to-gray coating free of powdery residue when applied correctly.
- Meets aggressive aerospace corrosion and adhesion specifications.
Applications
Recommended for touch-up and corrosion repair on magnesium aerospace parts before painting.
Technical Specs
- Operating temperature range: 60-100°F (15-37°C).
- Application: Brush on a clean, water-rinsed magnesium surface, maintain wet for 1-3 minutes, then rinse.
- Coverage depends on application technique; coating thickness is enough for corrosion resistance without excessive buildup.
- Contains hexavalent chromium; handle with appropriate PPE and ventilation.

Product 2: ALODINE M-CR 1200S (Brown, 10 lb Can)
ALODINE M-CR 1200S is a powdered chromate conversion coating that is commonly used for aluminum surface preparations, so structural repair shops will go through quite a lot of it. It produces a light, iridescent, golden, or even tan film that, once applied correctly, serves as a protective barrier to resist corrosion and promote paint adhesion.
Key Features of ALODINE M-CR 1200S
- It's certified to meet the QPL-81706 and MIL-DTL-5541 standards, which cover Class 1A and Class 3 coatings.
- Runs smoothly at 70-100°F - either a 15-second dip or a 3-minute spray will do the trick.
- The bath pH is tightly controlled between 1.3 and 1.8 by carefully adding nitric acid.

Product 3: M-CR 1132 Bonderite Touch-N-Prep (Yellow, 40 ml Pen)
This next product is different. The Bonderite Touch-N-Prep is a small pen that is to create dry-in-place conversion coatings. This is meant for quick touch-up work on small areas of aluminum, though it also works with some ferrous metals.
It is the perfect tool for field maintenance teams and AOG crews performing minor road surface repairs. This is great because it allows the preparation of small areas without entering surface treatment facilities.

Final Thoughts
Conversion coatings are another small but important piece of the overall corrosion protection and inhibition puzzle. They are also important for surface preparation to guarantee proper paint adhesion, which is no small deal; hundreds upon hundreds of gallons of paint are required for some jets in the fleet. Bad paint adhesion wastes money and time, and proper surface preparation is cheap insurance.
