Surface Preparation For optimum strength structural bonds, paint, oxide films, oils, dust, mold release
agents and all other surface contaminants must be completely removed. However,
the amount of surface preparation depends on the required bond strength and the
environmental aging resistance desired by the user.
Metals (Steel and Aluminum):
1. Wipe free of dust with oil-free solvent such as acetone or isopropyl alcohol.*
2. Sandblast or abrade using clean fine grit abrasives.
3. Wipe again with solvent to remove loose particles.
Aluminum Etching:
1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F ± 1F
(8C ± 5°C) for 10-20 minutes. Rinse immediately in large quantities of cold
running water.
2. Acid Etch: Place panels in the following solution for 10 minutes at 150°F ± F
(6C ± 2°C).
Sodium Dichromate 4.1 - 4.9 oz./gallon
Sulfuric Acid, 66°Be 38.5 - 41.5 oz./gallon
2024-T3 aluminum (dissolved) 0.2 oz./gallon minimum
Tap water as needed to balance
3. Rinse: Rinse panels in clear running tap water.
4. Dry: Air dry 15 minutes; force dry 10 minutes at 150°F ± 10°F (66°C ± C).
5. If primer is to be used, it should be applied within 4 hours after surface preparation.
Plastics/Rubber:
1. Wipe with Isopropyl Alcohol.*
2. Abrade using clean fine grit abrasives.
3. Wipe with Isopropyl Alcohol.*
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
and follow the manufacturers precautions and directions for use.
Handling
For short term storage (30 days), keep adhesive in a cool, dry place 60 to 80°F
(16-27°C). For long term storage, refrigeration (40°F [4°C] or below) is suggested.
Keep containers tightly covered and free of moisture. Polymerization is accelerated
by sunlight, so avoid direct exposure to sun. One Ounce Bottles: At end of day, clear
tip of dispensing nozzle by inserting a needle to prevent clogging. Wipe outside of
nozzle to remove excess adhesive with a folded non-cotton cloth or tissue. Replace
cap. One Pound Bottles: At end of day, remove cap-stem assembly and place
overnight in nitromethane or methyl ethyl ketone.* Seal bottle with shipping cap.
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
and follow the manufacturers precautions and directions for use.

Storage
Store in original containers at or below 80°F (27°C).
Shelf Life
These products can be expected to have at least nine months shelf life. At lower
temperature, the shelf life will be longer. Lower temperatures cause increased
viscosity of a temporary nature and also will cause water to condense on the
container. Therefore, containers stored at low temperatures should be allowed to
return to room temperature before opening so that water does not come in contact
with the adhesive and cause adhesive gelation.
