PPG Deft 03-GY-312 Flat Gray MIL-PRF-85285E Topcoat – 2 Gallon Kit
PPG Aerospace Deft 03-GY-312 is a flat gray (FS#36440) MIL-PRF-85285E Type I, Class H aerospace polyurethane topcoat — providing the specific FS#36440 flat gray color for military aircraft and defense systems where this particular gray shade is required by the applicable technical order. FS#36440 is a medium flat gray in the Federal Standard 595 color system used on certain aircraft types, helicopter airframes, and defense equipment paint schemes that specify this shade within the gray color family of military tactical coatings.
PPG’s comprehensive range of MIL-PRF-85285E qualified gray topcoats — each calibrated to a specific Federal Standard 595 gray designation — allows military paint shops to precisely match the color requirements of every aircraft type and technical order from a single, qualified coating supplier. The 2 gallon kit provides the production-scale volume needed for large-area painting operations on major aircraft sections, multiple component painting in depot operations, or facilities that prefer the 2 gallon kit size for their standard painting workflow.
Deft 03-GY-312 provides the full MIL-PRF-85285E performance profile: UV-stable aliphatic polyurethane, chemical resistance to military aircraft fluids, flexibility for long-term crack resistance, and consistent flat gray appearance maintenance through the aircraft’s service life between paint events.

Technical Information
Deft 03-GY-312 uses the PPG Deft MIL-PRF-85285E aliphatic polyurethane platform with the FS#36440 gray pigment formulation. The coating chemistry, mixing ratio, induction time, pot life, and application procedures are consistent with the Deft MIL-PRF-85285E product family, enabling military paint shops to apply all Deft gray topcoats using the same qualified application procedure — simplifying training and procedure documentation for facilities painting multiple aircraft types requiring different gray shades.
FS#36440 is in the medium-to-light gray range of the flat Federal Standard 595 gray family — slightly lighter than FS#36622 and FS#36293. This subtle shade difference is important for maintaining the correct tactical appearance of specific aircraft types for which FS#36440 is the designated tactical gray color. Using an adjacent gray shade outside the specification tolerance results in a non-conforming paint condition that must be corrected.
The 2 gallon kit should be mixed completely before use to ensure the full volume is at the correct ratio. Large batch mixing with a power drill and mixing paddle ensures thorough pigment dispersion and component integration throughout the gallon volume before spray application begins.
