The following product performance data was obtained in the 3M laboratory under
the conditions specified. The following data show typical results obtained with
Scotch-Weld epoxy adhesive DP110 Translucent and Gray when applied to
properly prepared substrates and cured for 48 hours at 73°F (23°C) under 2 psi
pressure and tested according to the specifications indicated.
Note: All data developed after a 48 hour cure @ 75°F (24°C) under 2 psi pressure
unless noted otherwise.
A. Aluminum Overlap Shear
Overlap shear strength was measured on FPL etched 1 in. wide by 1/2 in. overlap
specimens. The bonds were made from 2 panels of 4 in. x 7 in. x .063 in., 2024 T3
clad aluminum bonded together and cut into 1 in. wide specimens. The separation
rate of the testing jaws was .1 in./minute. Tests similar to ASTM D-1002.

C. Overlap shear on abraded metals, plastics, and rubber
Overlap shear strengths were measured on 1 in. wide 1/2 in. overlap specimens.
These bonds were made individually using 1 in. x 4 in. pieces of substrate.
The thickness of the substrates were: cold rolled, galvanized and stainless steel –
0.056-0.062 in., copper – 0.032 in., brass – 0.036 in., rubbers – 0.125 in., plastics –
0.125 in. All surfaces were prepared by solvent wiping/abrading/solvent wiping.
The jaw separation rate used for testing was 0.1 in. per minute for metals, 2 in. per
minute for plastics, and 20 in. per minute for rubbers.

Handling/Curing
Information Directions for Use
1. For high strength structural bonds, paint, oxide films, oils, dust, mold release
agents and all other surface contaminants must be completely removed from
substrates 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. For specific surface preparations on
common substrates, see the section on surface preparation.
2. These products consist of two parts.
Mixing
For Duo-Pak Cartridges
3M™ Scotch-Weld™ Epoxy Adhesive DP110 Translucent and Gray are
supplied in a dual syringe plastic duo-pak cartridge as part of the 3M™ EPX™
Applicator system. To use, simply insert the duo-pak cartridge into the EPX
applicator and start the plunger into the cylinders using light pressure on the
trigger. Next, remove the duo-pak cartridge cap and expel a small amount of
adhesive to be sure both sides of the duo-pak cartridge are flowing evenly and
freely. If automatic mixing of Part A and Part B is desired, attach the EPX
mixing nozzle to the duo-pak cartridge and begin dispensing the adhesive. For
hand mixing, expel the desired amount of adhesive and mix thoroughly. Mix
approximately 15 seconds after a uniform color is obtained.
For Bulk Containers
Mix thoroughly by weight or volume in the proportions specified on the product
label or in the uncured properties section. Mix approximately 15 seconds after a
uniform color is obtained.
3. For maximum bond strength apply product evenly to both surfaces to be joined.
4. Application to the substrates should be made within 8 minutes. Larger quantities
and/or higher temperatures will reduce this working time.
5. Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until
completely firm. Heat up to 200°F (93°C), will speed curing. These products will
fully cure in 48 hours @ 75°F (24°C).
6. Keep parts from moving during cure. Contact pressure necessary. Maximum shear
strength is obtained with a 3-5 mil bond line.
7. Excess uncured adhesive can be cleaned up with ketone type solvents.*
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
and follow the manufacturer’s precautions and directions for use.
Adhesive Coverage: A 0.005 in. thick bondline will typically yield a coverage of
320 sq. ft./gallon.

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.
