MIL-PRF-22750

MIL-PRF-22750 is a military specification that defines the requirements for two-part, high-performance epoxy coatings used on military equipment, particularly aircraft and vehicles. These coatings are designed for low volatile organic compound (VOC) content, with a maximum VOC content of 340 grams/liter (g/L), or 2.8 pounds/gallon (lb/gal), and provide protection against harsh environmental conditions, corrosion, chemicals, and abrasion.

Coatings conforming to this specification are supplied as kits and may be available in high gloss, semi-gloss, or lusterless finishes, as well as a wide range of colours. The most recent version of the spec is MIL-PRF-22750G, first established in 2011 with later amendments. The coating is lead- and chromate-free.

  • Colour options: Available in a wide variety of colours using FED-STD-595 colour chip numbers.
  • Low VOC content: Supports reduced harmful emissions, with a maximum VOC content of 340 g/L, or 2.8 lb/gal.
  • Excellent adhesion: Adheres to a variety of surfaces, including metal, composite materials, and wood.
  • Chemical and solvent resistance: Helps protect surfaces in harsh operating environments.
  • Weather resistance: Resists UV exposure, temperature extremes, and moisture.

Versions

MIL-PRF-22750G Is the most recent version of the spec where MIL = Military, PRF = Performance Specification, 22750 = Unique identification number, G = Version.

Types

Type I: Standard formulation with a maximumVOC content of 340 grams/liter (g/l) (2.8 pounds/gallon (lbs/gal)) as packaged.

Type II: Volatile organic hazardous air pollutants-free (VOHAP-free) formulation to meet the same maximum VOC content as Type I.

Type III: Direct to metal, VOHAP-free formulation to meet the same maximum VOC content as Type I. As a direct to metal, this coating will have enhanced corrosion performance including 1,000 hours salt spray and 40 cycles on the cyclic corrosion test. This type is only available in semi-gloss and lusterless colours.
