Hentzen's High-Solid Polyurethane Topcoat is a high-performance aerospace coating. This single-component base is qualified to the MIL-PRF-85285 Type I Class H specification.

This product is best suited for aviation and aerospace applications needing a durable, high-gloss, specification-qualified finish. In aviation, the topcoat is not just about appearance. It also must hold up against weather, chemicals, UV exposure, and demanding service conditions.

Common uses include aircraft exterior surfaces, where it is ideal for fixed-wing aircraft and helicopters that require a tough, glossy finish on the outer surfaces, such as fuselage sections, fairings, access panels, and other exposed components.

The white gloss topcoat is also well-suited for aerospace programs that require compliance with recognized military performance standards for polyurethane topcoats, where a clean, bright appearance is important, for visibility, heat reflectivity, UV resistance, or when a premium appearance matters.
