NPFC - MIL-PRF-32348
POWDER COATING, CAMOUFLAGE CHEMICAL AGENT RESISTANT SYSTEMS
|Publication Date:||16 December 2013|
This specification covers powder coatings for use on metallic substrates. Included are chemical agent resistant powder coatings for use as a finish coat and powder coatings meant for use as primers with chemical agent resistant camouflage finish coats on all military tactical equipment, which includes ground, aviation and related support assets. The materials are free of volatile organic compounds (VOCs), volatile organic hazardous air pollutants (VOHAPs) and inorganic hazardous air pollutants (HAPs), other than cobalt and non-hexavalent chromium.

Type I coatings are primer coatings applied and cured using the powder coat process. These primer coatings are intended for use on properly cleaned and pretreated steel and aluminum, meeting unique military requirements. These requirements include adhesion to a wide variety of metals, flexibility, corrosion resistance, and resistance to leaking fluids. Type II coatings are primer coatings designed for interior use as a one coat system having the corrosion resistance of the type I and having the color and gloss of the interior finishes. The color and gloss of the type II powder coat primer may be characteristic of the interior topcoat color as designated by FED-STD-595. Examples of the commonly used interior colors for tactical equipment are color numbers 17925 and 24533. Type III coatings are finish coatings applied and cured using the powder coat process. They are intended to provide surfaces that are easily and effectively decontaminated after exposure to liquid chemical agents. It may be used in areas where VOCs and VOHAPs are regulated. It is applied over epoxy primers conforming to the type I coating in this specification or MIL-DTL-53084. For adequate camouflage properties, it is necessary to apply the coatings to a minimum dry film thickness of 2 ± 0.2 mils (50 ± 5 microns).View Less
