Alexit ALEXIT404-12-71YL-7.008 (1-kg)

Additional Product Information

Overview

The ALEXIT FST-Strukturlack 404-12 is a solvent-based, two-component polyurethane topcoat designed for aircraft interiors. It provides both smooth and textured finishes, delivering rapid drying and high durability. Widely used in aviation MRO and production, teams rely on it for its exceptional resistance to wear, abrasion, contamination, and cleaning agents, while meeting strict aerospace FST (Flammability, Smoke, Toxicity) standards.

Why ALEXIT FST-Strukturlack 404-12 is Chosen for AOG / MRO

• Rapid drying for faster turnaround in maintenance operations
• High durability and chemical resistance ensure long-lasting surfaces
• Versatile application on smooth and textured surfaces
• Reliable OEM approvals reduce rework risk and ensure regulatory compliance
• Adaptable for both production and on-wing refurbishment projects

Practical Suggestions for Your Team (AOG Mindset)

• Stock base, hardener, and thinner in appropriate ratios for quick deployment
• Use white primer under bright or light colors for optimal coverage
• Ensure application staff are trained on spray pressures, nozzle sizes, and flow times
• Store containers within recommended temperature range to maintain pot life and shelf life
• Use fine Scotch-Brite pads to reactivate surfaces if recoating window is exceeded
