Additional Product Information
Overview
TOPCOAT XS420 is a three-component high-solid polyurethane topcoat designed for aircraft structural and external surface protection. Manufactured for aerospace finishing applications, it is widely used in aviation maintenance, repair, and overhaul (MRO) operations where chemical resistance, gloss retention, and long-term durability are required. Aviation teams rely on XS420 for professional exterior coating performance and reliable surface protection in demanding operating environments.
