NOTE

Openings may be oval, circular, square or rectangular with rounded

corners. Ensure core ribbon direction is same as panel.

Cut a core plug (2) and two aluminum patches (1) one to three inches larger all around than cutout

opening.

WARNING

Two part epoxy adhesive 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.

Mix a quantity of the adhesive in accordance with manufacturer's instructions, components (part "A" and

part "B") in an open top container sufficient to bond two patches (2) to core plug (1). 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.

WARNING

Methylethylketone is flammable and toxic and shall be used only in a

well-ventilated area away from sparks or open flame. Gloves and safety

goggles should be worn during use.

Wipe patches (2) with a clean cloth dampened with solvent and immediately wipe solvent from surfaces

with a clean, dry cloth.

Apply a thick coat of adhesive to one side of each patch.

Place core plug (2) between two patches (1) to create a sandwich panel (3).

Cure adhesive at room temperature (75 degrees F) for 72 hours. If a heat source is available, 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. Ensure that the surface temperature of the CBC does not exceed

225 degrees F.
