Methylethylketone is flammable and toxic and shall be used only in a
well-ventilated area away from all sparks or open flame. Gloves and
safety goggles should be worn during use.
Remove all traces of paint from damaged area (1) with sandpaper.
Wipe sanded surface with clean wiping rag dampened in solvent and immediately wipe solvent from
surface with a clean, dry wiping rag.
Mask sanded surface with masking tape (2).
Mix a quantity of the adhesive (3) in accordance with manufacturers instructions, components (part "A"
and part "B") sufficient for the scope of the repair in an open top container. The two adhesive components
are different colors; part "A" is yellow and part "B" is blue. When properly and completely mixed, the color
of the adhesive is green. Personnel should mix the two parts until the adhesive is a uniform green, with
no streaks of yellow or blue.
When performing a repair where injection of the mixed adhesive into the honeycomb core is not required,
it is applied directly from the container in which it is mixed.
Using a spatula or putty knife (4), fill damaged area (1) with adhesive (3).
Cure adhesive at room temperature (75 degrees F) for 72 hours. Alternate cures can be achieved by
exposing the repaired area to 150 degrees F for 3 to 4 hours, or 200 degrees F for 40 to 60 minutes. If
150 degree F or 200 degree F cures are used, allow additional time for repaired area to warm to curing
temperature and ensure that the surface temperatures of the CBC do not exceed 225 degrees F.
Sand surface of cured adhesive (3) to conform to surrounding area.
Remove masking tape (2) and clean repaired surface.
Apply alodine solution. Apply the alodine solution with a brush, paint spray gun, cellulose sponge, etc.,
to the cleaned and rinsed aluminum surface, liberally, quickly and evenly. Allow it to act from 1 to 5
minutes before rinsing.
The solution should be applied to only as much surface as can be coated and rinsed before the
alodine solution dries.
Proceed with the coating and rinsing until the entire surface is coated with alodine.
Rinse. Before the alodine solution dries, wipe it from the surface with a clean cloth or sponge wet with
clean water. The alodine solution may also be rinsed from the surface with clean water from a hose.
