TO 1-1-700 inactivity, storage, or shipment is known as non-operational preservation. 7.5.4 Types of CPCs. CPCs can be separated into two major categories: water displacing and non-water displacing compounds. 7.5.4.1 Water Displacing Compounds. Water displacing CPCs can be used to remove water, including sea water, or other electrolytes from metal surfaces. MIL-PRF-81309, MIL- PRF-63460, MIL-PRF-16173, Grade 3, and MIL-PRF-32033 are water displacing CPCs that are able to penetrate into cracks, crevices, voids at faying surface edges, around fastener heads, and into hinges. They usually provide very thin coatings, one mil (0.001 inch) or less in thickness, they are clear or translucent and remain soft and oily after application, so they cannot provide long term protection outdoors or in areas which are frequently handled. 7.5.4.1.1 Water Displacing, Hard Film. Another type, MIL-DTL-85054, differs from the other water displacing compounds as it doesn't penetrate into joints very well but forms a relatively hard, dry film on exterior surfaces; and therefore, it can be used for protection outdoors and in areas of frequent handling. 7.5.4.2 Non-Water Displacing Compounds. Non-water displacing CPCs may be used on dried surfaces or on wet surfaces which have been first treated with a water displacing CPC. MIL-PRF-16173, Grades 1, 2, and 4 are non-water displacing CPCs. They are heavier bodied waxy type greases which provide long term corrosion protection by forming a barrier film on metal surfaces. These CPCs provide thicker coatings and are light brown to very dark brown in color, with a waxy greasy appearance. They provide good corrosion protection and in areas where large amount of water collect on or run off of structures. 7.5.5 Time Limitations of CPCs. Because of their temporary nature, CPCs must be regularly removed and replaced to provide continuing corrosion protection. Table 7-3 provides the recommended time intervals for indoor and outdoor CPC use. Table 7-3. Time Limitations for CPCs CPC Outdoor 1 Indoor 2 Indoor Covered 3 Soft Thin Films MIL-PRF-81309, Type II 14 Days 30 Days 180 Days MIL-PRF-81309, Type III 5 Days 14 Days 90 Days MIL-L-87177, Grade B 5 Days 14 Days 90 Days MIL-PRF-16173, Grade 3 14 Days 30 Days 180 Days Lubrication and Protection MIL-PRF-32033 5 Days 30 Days 180 Days MIL-PRF-63460 5 Days 30 Days 180 Days Hard Thick Films MIL-DTL-85054 90 Days 210 Days 365 Days MIL-PRF-16173 Grade 4 90 Days 210 Days 365 Days MIL-PRF-16173 Grade 2 90 Days 210 Days 365 Days MIL-PRF-16173 Grade 1 210 Days 365 Days 365 Days 1 Outdoor: Without cover; exposed to elements in a mild climate; absence of rain and other washing forces; free from air and water borne pollutants. 2 Indoor: Hangars, shop areas, storage or parts accumulation areas, warehouses. 3 Indoor covered: Items are wrapped or sealed in a water-resistant material and stored indoors in a hangar, warehouse, or shop area. Soft thin film CPCs were designed for indoor use and ease of removal. 7-18
TO 1-1-700 7.5.6 Description of CPCs. A list of CPCs and their intended uses is summarized in Table 7-4. MIL-DTL-85054, MIL-PRF-63460, and MIL-PRF- 81309 have been revised to eliminate ODCs. Some reformulated products now contain flammable solvents and/or propellants. Pay close attention to all CAUTION/WARNING labels on the product containers as well as in their MSDSs. 7.5.6.1 MIL-PRF-81309; Corrosion Preventive Compound, Water Displacing, Ultra Thin Film and MIL-L- 87177; Lubricants, Corrosion Preventive, Water Displacing, Synthetic. MIL-PRF-81309 and MIL-L-87177 materials are general purpose corrosion preventive compounds for use when a thin, water displacing CPC is needed. MIL-PRF-81309 and MIL-L-87177 are for indoor protection and short term protection where surfaces can be re-coated when required. 7.5.6.1.1 These materials are excellent water displacing compounds which provide an ultra thin soft film (0.5 mils/ 0.0005 inch or less). The MIL-PRF-81309 specification covers two types of materials and the MIL-L-87177 specification covers one grade of material that are useful for Air Force purposes to provide temporary protection from corrosion while still being easily removable with solvent. 7.5.6.1.2 They should not be used around liquid oxygen fittings. All of these CPCs may be applied by dipping, brushing, or spraying with a pump or aerosol sprayer. 7.5.6.2 MIL-PRF-81309, Type II and MIL-L-87177, Grade B. These CPCs form a soft, thin film for general use on moving or sliding parts where some lubrication is needed, such as on hinges. These materials can be easily washed away by rain or wash procedures, so frequent reapplication may be required. They are useful in the protection of areas which cannot be properly drained or contain recesses that are particularly difficult to reach due to their excellent water displacing abilities. 7.5.6.3 MIL-PRF-81309, Type III and MIL-L-87177, Grade B. These CPCs form an ultra thin, soft film that provides excellent water displacement and corrosion protection for the interior of electrical, avionics, and other electronic equipment and connectors. Although these CPC coatings are non-conductive, they will allow electrical contact because their very soft, thin film is easily moved aside by mechanical action or contact. These materials are the only CPCs allowed for the interior use on electrical and electronic equipment. 7.5.6.4 MIL-DTL-85054 Corrosion Preventive Compound, Clear. MIL-DTL-85054 is a water displacing CPC which forms a clear, hard/dry, semi-flexible film. It is intended for use as a protective coating on bare metal areas where the paint system has been damaged or failed until touchup and/or repainting are practical. Because of its paint-like characteristics, it provides no lubrication and blocks electrical conductivity. NOTE • MIL-DTL-85054 can be applied by dipping, brushing, or spraying with a paint spray gun or an aerosol can; but it is primarily applied by spraying from aerosol cans. Invert the aerosol can after each use and spray to clear the spray tip (nozzle) of entrapped material. • If an aerosol can does not spray, invert and depress the spray tip several times to clear the delivery tube and spray tip (nozzle). • If the can still does not spray, remove and clean the plastic spray tip (nozzle) and then reinstall the spray tip (nozzle) and spray again to clear the delivery tube. • Dip application provides only a very thin coating and therefore much less corrosion protection. • Remove MIL-DTL-85054 if it is damaged due to abrasion, there are cracks in the coating, or if there is evidence of corrosion under the coating. • Since excessive MIL-DTL-85054 buildup is difficult to remove, especially after prolonged exposure to direct sunlight, remove previously applied coatings before reapplication. If the solvents recommended in Table 7-5 do not remove old films of MIL-DTL-85054 , spraying on fresh MIL-DTL- 85054 to soften the film and wiping or rubbing while wet is often effective. 7.5.6.5 MIL-PRF-16173 Corrosion Preventive Compound, Solvent Cutback, Cold Application. MIL-PRF- 16173 covers five different grades of CPCs, four which can be applied by brushing or dipping. Grades 1, 2, and 4 do not displace water and must be applied to dried surfaces after joint areas have been treated with MIL-PRF-81309, Type II or III, MIL-L-87177, Grade B or MIL-PRF-16173, Grade 3 to penetrate into the joints.
