MOLYKOTE-D-321R-AEROSOL (400-ml-Aero)

Additional Product Information

Overview

MOLYKOTE-D-321R-AEROSOL is trusted by MRO teams and aircraft engineers worldwide for delivering reliable dry-film lubrication in the most demanding aerospace environments. Its molybdenum disulfide and graphite formula reduces friction, prevents wear, and ensures components operate safely and consistently. The 400 ml (13.52 fl. oz.) aerosol is lightweight, clean, and fast-drying, making it ideal for hangars, AOG kits, and maintenance stockrooms.

Key Technical Specs

• Type: Air-curing dry-film anti-friction coating with solid lubricant in a solvent binder; forms a thin, hard lubricating film.
• Can Size: 400 ml (~13.52 fl. oz.) aerosol.
• Film Thickness / Application: Touch-dry in ~5 minutes at 23°C (73.4°F); functional lubrication develops shortly after application.
• Performance: Metal-on-metal contacts at slow to medium sliding speeds and high loads. Reduces stick-slip, resists wear, and tolerates extreme environments.

Approvals & Specifications

• Widely accepted in aerospace MRO contexts; listed in aviation supply channels. Confirm acceptance for specific airframe/engine components with OEM or SRM.
• Supplier/OEM references indicate applicability for engines, airframe parts, and critical systems. Always verify part acceptance before use.

Typical Aircraft MRO / AOG Applications

• Sliding guides, pins, bushings, sleeves, valve stems, actuator slides, threaded fasteners, gear teeth, high-voltage switches, rotor head emergency lubrication, and other metal-to-metal interfaces.
• Aerosol format allows immediate, clean application for emergency repairs, fast turnarounds, and sensitive system maintenance. Dry film resists dirt pickup and reduces rework.

Compatibility & Safety Notes

• Substrate Prep: Clean/degrease; optional phosphatizing or light abrasive blasting enhances adhesion and film life.
• Lubricant Compatibility: Intended as a dry solid lubricant; use where dry film is preferred over oils or greases.
• Hazards / SDS: Aerosol is flammable; vapors may cause dizziness; aquatic toxicity noted. Use in well-ventilated areas or outdoors with PPE. Follow fire, spill, and disposal protocols.

Packaging & Procurement

• Single 400 ml aerosol can, commonly sold in cartons. Transport classification: UN1950 (consult SDS). Suitable for aircraft use and AOG/MRO stock.

Why Chosen for AOG / MRO

• Fast, clean application ideal for emergency fixes and hard-to-reach components.
• Dry film avoids contamination, dust pickup, and migration into sensitive systems.
• High load capability with stick-slip prevention ensures smooth operation until scheduled maintenance.

Practical Suggestions (AOG mindset)

• Keep several aerosol cans in each AOG trolley or kit.
• Maintain TDS and SDS in the kit and on shop walls for immediate reference.
• Test on small areas first for critical components; record usage in maintenance defect cards.
• Train ground crew in ventilation, PPE, and safe disposal of pressurized cans.
