MIL-STD-171F

5.3.5 Applications of GARG/camouflage systems. Unless otherwise specified Green 383 paint shall be applied over the specified primer at a minimum dry film thickness of 1.8 mils to achieve optimum infrared camouflage characteristics. An application of 0.8-1.2 mils dry, which is the normal thickness for a paint topcoat, will only provide visual camouflage. In summary, the 1.8 mil minimum requirement provides visual and infrared camouflage as well as chemical agent resistance. Texture and type of substrate may cause variation in appearance. The acceptance

of the coating shall not be based specifically on color (see 6.10).

5.3.5.1 Primer. Primer requirements include thickness, adhesion and corrosion resistance for carbon and low alloy steels. See tests in Section 6.

5.3.5.2 Top coat. Top coat requirements include thickness, adhesion and "degree of cure" for all substrate material. See tests in Section 6.
