Epoxy Adhesives

DP110 Translucent and Gray

Application Equipment

Suggestions

These products may be applied by spatula, trowel or flow equipment.

Two part mixing/proportioning/dispensing equipment is available for intermittent or

production line use. These systems are ideal because of their variable shot size and

flow rate characteristics and are adaptable to many applications.

Surface Preparation

For high strength structural bonds, paint, oxide films, oils, dust, mold release agents

and all other surface contaminants must be completely removed from substrate to be

bonded. However, the amount of surface preparation necessary directly depends on

the user’s required bond strength, environmental aging resistance and economic

practicalities.

The following cleaning methods are suggested for common surfaces:

Steel:

1. Wipe free of dust with oil-free solvent such as acetone or isopropyl alcohol

solvents.*

2. Sandblast or abrade using clean fine grit abrasives.

3. Wipe again with solvent to remove loose particles.*

4. If a primer is used, it should be applied within 4 hours after surface preparation.

Aluminum:

1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F ± 10°F

(88°C ± 23°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 ± 5°F

(66°C ± 23°C).

Sodium Dichromate

4.1 - 4.9 oz./gallon

Sulfuric Acid, 66°Be

38.5 o 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 ± 23°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 fine grit abrasives.

3. Wipe with isopropyl alcohol.*

*Note: When using solvents, extinguish all ignition sources, including pilot lights,

and follow the manufacturer’s precautions and directions for use.
