BONDERITE® 1200 Powder Coating

BONDERITE M-CR 1200S AERO — Product Overview & Working Principle

BONDERITE 1200 is not a paint or primer. It is a chemical surface treatment that converts the top layer of aluminium into a protective chromate film. The kit consists of three components: Powder Part P (MP0476), Acidic Base Part L (MP0477), and Neutraliser Part N (MP0478) for safe disposal of mixed material.

How It Works (High-Level Principle)

When Powder Part P is dissolved in the Acidic Base, a controlled chemical reaction occurs on clean, oxide-free aluminium. Instead of forming a deposited layer, the process modifies the metal surface itself, producing an integral chromate conversion coating of 0.3–2.0 g/m². This chemically bonded layer is flexible, impact-resistant, and provides a strong foundation for subsequent paint systems.

Why This Matters in Real MRO Work

In aircraft maintenance, large dip tanks are not always practical for small parts or localized repairs. BONDERITE 1200 allows technicians to treat specific areas by brush or swab, reducing rework, saving time, and maintaining compliance with aerospace standards while still achieving controlled corrosion protection.

Technical Information

• Product Type: Chromium conversion coating (powder-based brush kit)
• Process Type: Rapid, non-electrolytic chemical conversion treatment
• Appearance of Coating: Iridescent golden film
• Substrate Compatibility: Clean, oxide-free aluminium and aluminium alloys
• Mixing Ratio: 25 g Powder Part P (MP0476) into 1 litre Acidic Base Part L (MP0477)
• Pot Life (Mixed Material): Up to 24 hours under normal working conditions
• Application Method: Brush or swab
• Recommended Tools: Nylon brush, soft bristle brush, or sponge
• Suitable Equipment: Plastic or stainless steel mixing containers (no glass, tin, mild or galvanized steel)
• Disposal Control: Neutraliser Part N (MP0478) converts toxic hexavalent chromium to non-toxic trivalent chromium before disposal

Technical Specifications

Certifications & Standards

• SAE AMS 03-18
• MIL-DTL-5541
• MIL-DTL-81706
• DEF STAN 03-18

These approvals make BONDERITE 1200 suitable for regulated aerospace, defense, and aviation MRO environments where documented compliance is required.

Applications

• Aircraft MRO & Maintenance: Localized repair of Alocrom-treated or anodized surfaces where dipping is not feasible.
• Aerospace Component Overhaul: Treatment of small aluminium parts prior to primer or topcoat application.
• Manufacturing & Assembly: Spot treatment of machined aluminium areas before bonding or painting.
• Quality & Compliance Teams: Suitable where conformance to AMS/MIL/DEF STAN specifications is required.

How to Use (Practical Steps)

1. Clean: Remove heavy oils with a suitable degreaser.
2. Deoxidise: Treat with Bonderite C-IC 624 (MP0003).
3. Rinse: Cold water rinse and allow to drain.
4. Mix: Dissolve 25 g Powder Part P in 1 L Acidic Base Part L.
5. Apply: Brush or swab evenly; allow 15 seconds to 3 minutes reaction time.
6. Rinse: Cold water rinse from top to bottom.
7. Dry: Air dry or use warm air up to 60°C.
8. Dispose: Neutralize excess with Part N until solution turns green.

Handling, Storage & Regulatory Notes

• Store all three components separately in original, unopened containers in a cool, dry area.
• Once mixed, use within 24 hours and do not return excess to a closed container.
• For disposal, always add Neutraliser Part N until the solution turns green before releasing diluted waste.
• Refer to individual Safety Data Sheets before use.
• Shelf life details are printed on product labels.

Frequently Asked Questions

Q1. How long is the mixed product usable?
Up to 24 hours. Excess mixed material should be neutralized and discarded.

Q2. Can this be used by dipping?
It is primarily designed for brush/swab application where dipping is not commercially viable.

Q3. Is this compatible with aircraft paint systems?
Yes. It provides an excellent base for subsequent primer and paint systems.

Q4. What if bare patches appear after treatment?
This usually means inadequate pre-cleaning. Re-clean with Bonderite C-IC 624 and reapply.

Q5. Is neutralization mandatory before disposal?
Yes. Neutraliser Part N must be used to reduce hexavalent chromium before disposal.

Q6. What substrates can it be used on?
Clean, oxide-free aluminium and aluminium alloys only.
