Characteristics

TM 43-0139 (3) Application. Spray at a temperature of 65°F ±5 F (18.33°C ±2.78°C), with a tank pressure of 80 pounds per square inch (psi) and with no more than 80 psi on the gun nozzle. d. Paint, Heat-Resisting, Silicone-Aluminum (TT-P-28). (1) Characteristics. This is a one-type and one-grade, aluminum, heat resistant paint which will withstand solvents and normal weather exposure. It is an air-drying, or air-drying and baking, product with an aluminum pigment of powder or paste, suspended in a liquid vehicle. (2) Use. It is used for painting equipment where operating temperatures preclude the use of conventional paints and for applications where engraved, stamped, or stenciled lettering would be exposed to temperatures up to 1000°F (537°C). (3) Application. Spray as issued; brush when required. e. Paint, Heat-Resisting (For Steel Surfaces) (MIL-P-14105). (1) Characteristics. This paint contains a blend of ceramic frits, refractories, and pigments in a vehicle of pure or modified silicone resins. (2) Use. This paint is intended for use on solvent degreased and blasted steel surfaces of components which are subject to temperatures as high as 1,400°F (760°C) and exterior weathering. Components such as mufflers, manifolds, and stacks may be protected by the use of this paint. The paint provides excellent protection against corrosion and chemical attack. It has also been found to perform satisfactorily when applied to parts that do not lend themselves to sand blasting. In application to such parts, however, it is absolutely necessary that all loose rust and tight and loose mill scale be removed by wire brushing and chipping. Coatings should then be applied by brushing, taking care to work the paint well into the roughened surfaces. (3) Application. Apply by brushing as received, or by spraying reduced in accordance with manufacturer's recommendations. (4) Drying Time. Paint air dries tack-free within 1 hour. Dries hard when baked at 400°F (204°C) for 30 minutes. f. Coating, Red Fuming, Nitric, Acid-Resistant (MIL-P-22636 and MIL-P-14458). (1) Characteristics. This coating consists of a primer conforming to MIL-P-22636 and a paint conforming to MIL-P-14458. (2) Use. When using red fuming, nitric, acid-resistant coating, refer to the specifications on this material. These are listed in the Reference appendix in the back of this publication. g. Paint, Stencil, Flat (TT-P-98). (1) Characteristics. Stencil paint is of one grade and two types. The paint-consistency type comes in black, white, and gray primary and secondary colors; the paste-form type comes in black, white, red. and yellow colors. (2) Use. For marking bales, crates, fiberboard boxes, ammunition, etc. (3) Application. Apply with a brush and stencil board, or mask to surfaces of varying textures and absorptive properties. 2-17
