• Safety: UN1263, Class 3, Packing Group II. Flammable. Use in well-ventilated areas with appropriate PPE.

Packaging & Procurement

• Aerospheres Offering: 1.25 US gallon (4.73 L / 12.4 lbs.) kit.
• Contains: 4 parts base (4002-A21M) + 1 part curing solution (0200T106). Optional thinner up to 1 part.
• Shipping Weight / Dimensions: ~15 lbs., 11 x 7 x 8 in.
• Shelf Life: 12 months under recommended storage conditions.
• Ideal size for hangar or MRO floor storage. Enough for multiple leading edges without waste.

Why AkzoNobel 4002-A21M/0200T106 is Chosen for AOG / MRO

• Fast application and curing allow quick turnaround in critical aircraft repair scenarios.
• Prevents extended grounding due to leading edge erosion or pitting.
• Reduces long-term maintenance costs by extending substrate life.

Practical Suggestions (AOG Mindset)

• Keep at least 1–2 kits per hangar or AOG response kit.
• Pre-check anodized surface timing. Apply within 16 hours of anodizing or abrade lightly before use.
• Use induction time (~30 minutes) for best coating consistency.
• Train ground crew for proper spray technique to maximize coverage and performance.
