PPG Deft 03-GY-323 Flat Gray MIL-PRF-85285E Topcoat – 2 Gallon Kit

PPG Aerospace Deft 03-GY-323 is a flat gray MIL-PRF-85285E Type I, Class H aerospace polyurethane topcoat in the 2 gallon kit format — another gray shade in PPG’s comprehensive range of MIL-PRF-85285E qualified flat gray aerospace topcoats, providing the specific gray color required by certain military aircraft technical orders. The availability of multiple FS gray shades in the Deft product range enables military paint shops to stock and apply the correct, specification-verified gray shade for each aircraft type and component area in their maintenance program.

The 2 gallon kit format is selected for operations requiring more than a standard gallon per painting session — whether due to larger surface area requirements, production efficiency in reducing mixing operations, or facility preferences for the 2 gallon batch size in their standard paint mixing workflow.

All PPG Deft MIL-PRF-85285E topcoats provide the same high-performance aliphatic polyurethane foundation — UV stability, chemical resistance, flexibility, and weathering durability — with the specific color formulation providing the approved shade for each FS designation. The consistent performance across the color range simplifies qualification and application procedure development for military paint facilities operating on multiple aircraft types.

Technical Information

Deft 03-GY-323 is formulated on the Deft MIL-PRF-85285E aliphatic polyurethane platform with the 03-GY-323 color formulation producing the specific gray shade required by the applicable technical order. Application and performance properties are consistent with other MIL-PRF-85285E Deft topcoats — the same mixing ratio, induction time, pot life, spray application procedure, and film thickness targets apply across the color range.

The flat matte appearance is achieved through matting agents as in other flat Deft products. The 60-degree gloss reading of the cured film must fall within MIL-PRF-85285E’s flat category specification window. Verify gloss compliance with the applicable test method after cure if gloss specification compliance documentation is required for the aircraft’s maintenance record.

The 2 gallon batch should be fully mixed to ensure color consistency throughout. The gray pigment blend must be thoroughly mixed into the polyol base before adding the hardener — inadequate mixing of the base can result in color streaking or variation in the applied film.
