PPG Deft 03-BK-099 Flat Black MIL-PRF-85285E Aerospace Polyurethane Topcoat – 2 Gallon Kit
PPG Aerospace Deft 03-BK-099 is a flat black (FS#37038), high-performance aerospace polyurethane topcoat qualified to MIL-PRF-85285E Type I, Class H — the premier U.S. military specification for flexible, chemically resistant polyurethane topcoats used on military aircraft, helicopters, and defense systems. MIL-PRF-85285E polyurethane topcoats represent the highest performance standard for military aerospace exterior coatings, providing superior flexibility, chemical resistance, UV durability, and gloss/flat retention compared to the epoxy topcoats of earlier military coating generations.
The flat black FS#37038 color designation is used extensively on military aircraft for low-visibility areas, anti-glare zones, equipment markings, and surfaces where a matte, non-reflective black finish is required for tactical or aesthetic purposes. The 2 gallon kit provides the volume required for significant painting operations on military aircraft — wing areas, fuselage sections, and large structural components where sustained topcoat application is performed during depot-level maintenance events.
Deft 03-BK-099 delivers the exceptional weathering resistance, chemical resistance, and appearance retention that MIL-PRF-85285E topcoats are known for, protecting aircraft structure from the corrosive environment of military operational service worldwide.

Technical Information
Deft 03-BK-099 MIL-PRF-85285E Type I, Class H is a two-component aliphatic polyurethane topcoat produced from the reaction of a hydroxyl-functional polyol base with an aliphatic isocyanate hardener. The aliphatic isocyanate chemistry provides superior UV resistance and color stability compared to aromatic isocyanate systems — maintaining the flat black color and matte finish appearance over the extended outdoor exposure cycles of military aircraft service without the chalking and fading that occurs in aromatic polyurethane and epoxy topcoats under UV radiation.
Class H in MIL-PRF-85285E designates a high-solids, low-VOC formulation that reduces solvent emissions during application while achieving the specified dry film thickness range with fewer coats. This environmental performance advantage is increasingly important in military depot facilities subject to air quality permits and solvent emission restrictions.
The 2-component system must be mixed in the correct ratio and used within the specified pot life. Application requires proper spray equipment set-up, appropriate environmental conditions, and film thickness control per the PPG Deft PDS and applicable military technical order for the aircraft being painted.
