MIL-C-40084C

Abstract

This specification covers a fire-resistant, water-emulsifiable, oil type corrosion preventative compound to be used as a rust inhibiting coating. <b><u>Intended Use:</u></b> The water emulsifiable corrosion preventive compound covered by this specification is intended for use whenever a low-cost, fire-resistant, soft-film, corrosion preventive can be utilized. The compound is formulated to be emulsified in distilled or de-ionized water, normally at a 1 to 4 ratio, reducing the volatile content of the corrosion preventive to a minimum. Maximum corrosion resistance is obtained as a dry finish over zinc phosphated surfaces at 20 to 30% by volume concentration. Immersion is used for maximum protection, however, spraying at low concentratons can be used for in-plant protection of metal surfaces. It is designed to be used over massive zinc phosphated coatings to produce a dry-to-touch corrosion resistant film. It has proven efficient for use on small hardware or parts of uniform contour. Overheating for extended periods of time will reduce the efficiency of the emulsifiers. When using at 120&#176;-140&#176;F, (49&#176;-60&#176;C) 3 minutes is optimum. <br>
