• Base material: 6 kg and 12 kg containers (US gallon and quart equivalents available)
• Hardener: 1 kg containers (US pint and quart options available)
• Storage temperature recommended between 5°C and 35°C (41°F and 95°F)
• Protect from frost during transport and storage

Why ALEXIT FST-Topcoat 346-57 is Chosen for AOG / MRO

• Rapid drying performance supports time-critical maintenance and return-to-service targets
• Excellent abrasion and contamination resistance extends cabin surface life
• Flexible application methods allow single-layer smooth or two-layer textured finishing
• Waterborne formulation supports environmentally responsible maintenance operations
• OEM-qualified compatibility reduces certification and integration risk

Practical Suggestions for Your Team (AOG Mindset)

• Maintain stock of base material and hardener for emergency cabin repair scenarios
• Observe flash-off time of 45–60 minutes before oven curing when required
• If recoating window is exceeded (3–48 hours), lightly reactivate surface using fine-grade abrasive pad
• Follow equipment manufacturer nozzle and pressure recommendations for spraying consistency
• Train technicians on mixing sequence: pre-dilute base with water → add hardener → mix for at least 1 minute
