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.

Drill two 1/8 inch (3.18 mm) diameter holes (1) within damaged area.

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.

To inject the mixed adhesive into the honeycomb core, adhesive (3) must be loaded into an empty 1/10

gallon cartridge. To load the mixed adhesive into the empty cartridge, first install a nozzle onto the end of

the empty cartridge, then scoop a quantity of mixed adhesive onto the putty knife and place into the open

end of the cartridge. Load a sufficient amount of adhesive into the cartridge for the scope of repair. When

the adhesive is completely loaded into the cartridge, install the end cap. Install the cartridge into a

standard caulking gun (2).

Inject adhesive through two drilled holes (1) to fill core cells completely. Tape over holes in order to hold

the adhesive in place during the curing process.

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.

Check by tapping damaged area to ensure complete filling of cells.

Sand damaged area with sandpaper to remove all traces of paint and excess adhesive.

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.
