Apply a mixture of one part TT-I-735, Isopropyl Alcohol, and one part distilled water to affected areas with a CCC-C-46 Cleaning Cloth; an A-A-289 (style optional) Acid Brush; a toothbrush or other type soft, non-metallic bristle brush as appropriate. b. Wipe or scrub affected area until contaminants have been dislodged. c. Remove residue by blotting or wiping with a CCC-C-46 Cleaning Cloth. Inspect affected areas for signs of residues and contaminants. d. Discard contaminated cloths and solvents in approved disposal containers after cleaning operation to avoid contamination of other components. MIL-L-87177, LUBRICANT, CORROSION PREVENTIVE COMPOUND, WATER DISPLACING 32 10.12 ELECTRICAL COMPONENTS AND OTHER COMPONENTS. Almost all corrosion problems on electrical and electronic equipment are caused by moisture intrusion at the connector or lead-in attachment points on cases and covers. While the design of this equipment is fixed, corrosion can be prevented by spraying MIL-PRF-81309, Type III or MIL-L-87177, Type I, Grade B Avionics Grade, Water Displacing CPC into the pin and/or pin receptacle end of the connectors prior to mating the connector halves, and on the connector shells after mating the connector halves. Consult Chapter 7 of TO 1-1-691 for corrosion protection of electrical connectors and Chapter 6 of TO 1- 1-689-3 for cleaning and preservation. Potting compounds are also used to protect electrical connectors from corrosion, contamination and arcing by the exclusion of moisture, stray particles, and liquids. Chapter 8 of this manual provides the recommended potting compounds to use. 10.13 BONDING/GROUNDING. Electrical bonding provides a low resistance electrical path between two or more conductive units or components. Grounding is a form of bonding that utilizes the primary structure as a portion (return path) of the electrical circuit (see Figure 10-11). See Chapter 1 of TO 31-1-75 and Chapter 8 of this manual for further information on grounding. Bonding may serve one or all of several functions: a. Provide a common ground for the proper electrical functioning of the units involved. b. Provide a path to minimize lightning strike damage. c. Prevent the buildup of static potentials that could result in a spark discharge. d. Minimize static and stray currents in units involved. e. Prevent a unit from emitting electromagnetic energy that would interfere with other units and provide a signature for enemy detection and recognition. 10-10 Change 3
TO 1-1-700 f. Shield equipment from outside electromagnetic interference (EMI) sources. metal (galvanic) corrosion often occurs at antenna attach points. Inspection and treatment processes are outlined in Chapter 6 of TO 1-1-689-3. Refer to the system specific maintenance manuals for information on paint touch-up and finishing. Apply paint and coatings per procedures in TO 1-1-8. Figure 10-11. Bonding Cable Between Frame and Door 10.13.1 Corrosion Prevention and Treatment for Grounding and Bonding Connections. The bonding and grounding straps used on communications and electronics equipment are highly susceptible to galvanic corrosion. In most cases, the bonding or grounding strap is made of a metal that is dissimilar to the mating surface. This creates a galvanic couple that in the presence of moisture will corrode rapidly. MIL-PRF-81733, SEALING AND COATING COMPOUND, CORROSION INHIBITIVE 48 10.13.2 Electrical Bonding/Grounding. See Chapter 8 of this manual for the corrosion control measures for electrical bonding/grounding, which describes the best hardware and techniques to be used when cleaning, repairing or replacing existing connections. After the grounding or bonding connection has been made, overcoat the entire connection, including all bare areas on the metal surface, with MIL-PRF-81733, Type II, Class 1 or 2, Grade A sealant (see Chapter 8 of this manual for additional information). See TO 00-25-234 for proper procedures to be used in external earth grounding of permanent and portable structures. 10.14 ANTENNAS AND RADAR SURFACES. Antenna and radar dish surfaces, hardware, connectors and electronic systems are normally exposed to fairly severe environments with dissimilar (galvanic) corrosion occurring at antenna attachment points (see Figure 10-12). Without adequate corrosion protection, these systems can fail via shorts, open circuits, loss of dielectric strength, signal attenuation, poor bonding, or electromagnetic interference (EMI). The area around the antenna mounting to a shelter or van is susceptible to moisture intrusion from rain and condensation. Dissimilar Figure 10-12. ANTPS-75 Antenna Radar Surface 10.15 VAN AND TRAILER UNDERCARRIAGES. 10.15.1 Shelter Underbody. The undercarriage or underbody of tactical shelters are susceptible to corrosion (see Figure 10-13). Inspect the underbody coating for chipped, cracked, or loose coating and bare metal. If the deficiency is determined to warrant repair, see the system specific shelter maintenance manual for cleaning, repair, treatment, and painting. MIL-T-81772, THINNER, POLYURETHANE 70 Blowing dry air or nitrogen to evaporate solvent can create airborne particles which may enter the eyes. Air pressure for drying shall not exceed 30 PSI at the nozzle. Eye protection is required. Failure to comply may cause personnel injury resulting form exposure to airborne particles. a. Completely clean the undercarriage. Scrape off defective coating using a putty knife and Specification MIL- T-81772, Type I, Polyurethane Coating thinner. b. Mask affected areas in accordance with TO 1-1-8. 10-11
