    Additional Product Information

    Overview

    TOPCOAT XS420 is a three-component, high-solid polyurethane topcoat engineered for aircraft structural and exterior protection. Designed for use in aerospace OEM and MRO environments, it delivers high chemical resistance, excellent gloss retention, and long-term durability over properly prepared and primed metallic substrates. When used in combination with approved epoxy primers such as SP350, it forms a high-performance protective system relied upon by aviation maintenance and production teams worldwide.
