ELECTROMAGNETIC CONDUCTIVE COATING APPLICATION
2.34.6. Repair
a. Repair aluminum parts.
NOTE
This repair procedure is for existing conductive coatings on aluminum surfaces in need of repair.
Do not touch up surfaces longer than 6.00 INCHES. If longer, reapply conductive coating to entire
surface.
(1) Aluminum surfaces that are scratched and/or have corrosion protective coating damage, shall have
chemical conversion coating applied (TM 55-1500-344-23). Use corrosion resistant coating (item 66,
App F).
NOTE
Do not leave more than 0.25 INCH of conductive paint exposed around the perimeter of the repair
area.
(2) Mask off conductive paint to protect it from chemical conversion coating. Use tape (item 205, App F).
CAUTION
Ensure not to soften or damage existing coating during cleaning.
(3) Clean area to which conductive coating will be applied. Use isopropyl alcohol (item 106, App F) and cloth
(item 52, App F).
(4) Apply a coat of chemical conversion coating. Use brush (item 36, App F) and corrosion resistant coating
(item 66, App F).
(5) Dry surface with cloth, then wipe with a alcohol dampened cloth to accelerate drying process. Allow
surface to dry. Use isopropyl alcohol (item 106, App F) and cloth (item 52, App F).
(6) Remove tape and lightly sand paint surface next to the surface exposed to the chemical conversion
coating. Use cloth (item 48, App F).
(7) Clean sanded area. Use isopropyl alcohol (item 106, App F) and cloth (item 52, App F). Ensure all tape
adhesive has been removed.
