Additional Product Information

Overview

ALEXIT FST-Strukturlack 404-12 is a solvent-based, two-component polyurethane structural topcoat designed for aerospace cabin interior finishing. It is widely used in aviation manufacturing and maintenance, repair, and overhaul (MRO) operations where fire safety, durability, and surface aesthetics are critical. Aircraft engineering teams rely on this coating because it combines FST regulatory compliance with strong mechanical resistance and decorative surface quality for modern cabin environments.
