PPG Deft 03-GY-310 Flat Gray MIL-PRF-85285E Topcoat – 2 Gallon Kit
PPG Aerospace Deft 03-GY-310 is a flat gray (FS#36251) MIL-PRF-85285E Type I, Class H aerospace polyurethane topcoat in the 2 gallon kit format. FS#36251 is a specific flat gray in the Federal Standard 595 color system used on certain military aircraft, helicopters, and defense systems where the paint scheme technical order specifies this particular gray shade — distinct from FS#36622 and FS#36293 in the subtle color range that distinguishes the different military flat gray designations.
The 2 gallon kit is selected for larger painting operations requiring more material than the standard gallon format — significant aircraft sections, multiple component painting in a single session, or facilities where the 2 gallon format improves mixing efficiency and reduces downtime between kit preparations during high-throughput painting operations.
All PPG Deft MIL-PRF-85285E topcoats share the same high-performance aliphatic polyurethane chemistry, with batch-to-batch color consistency controlled to match the Federal Standard 595 reference for the specific FS color code. The military paint finish achieved with 03-GY-310 will match the specified FS#36251 color within the tolerances of the MIL-PRF-85285E specification.

Technical Information
Deft 03-GY-310 is formulated on the same aliphatic polyurethane platform as other Deft MIL-PRF-85285E topcoats, providing consistent physical and chemical performance properties across the entire color range. The FS#36251 color formulation uses gray pigment blends — typically carbon black and titanium dioxide with other color modifiers — calibrated to produce the specific gray shade of FS#36251 as defined by the Federal Standard 595 color chips. Batch-to-batch pigment control ensures consistent color matching across production lots.
The flat matte appearance of FS#36251 is achieved through matting agents as in other Deft flat gray products. The 60-degree gloss reading of the cured coating must fall within the range specified by MIL-PRF-85285E for the flat gloss category to confirm specification compliance — too high a gloss reading indicates insufficient matting agent or application technique issues.
The 2 gallon kit should be mixed completely before use to ensure correct ratio throughout the batch. Store unused mixed material in a sealed container and use within the specified pot life — do not add fresh unmixed material to a partially used mixed batch, as this disrupts the ratio and can produce an incompletely cured coating.
