Handling/Application

Information

Directions for Use

For high 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 necessary depends on the required bond strength and the

environmental aging resistance desired by user. For specific surface preparations on

some common substrates, see the section on surface preparation.

3M™ Scotch-Weld™ Epoxy Adhesive DP100 FR is 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 simultaneous mixing of Part A and Part B is desired, attach the

EPX mixing nozzle to the duo-pak cartridge and begin dispensing the adhesive.

When mixing Part A and Part B manually, the components must be mixed in the ratio

indicated in the Physical Uncured Properties section. Thorough mixing of the two

components is required to obtain optimum properties.

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

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

size and flow rate characteristics and are adaptable to most 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. However, the

amount of surface preparation necessary depends on the required bond strength and

the environmental aging resistance desired by user.

The following cleaning methods are suggested for these common surfaces:

Steel:

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

solvents.*

2. Sandblast or abrade using clean fine grit abrasives.

3. Wipe again with solvent to remove loose particles.

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

follow manufacturer’s precautions and directions for use.

Aluminum:

1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F (88°C)

± 10°F (-13°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 (66°C)

± 5°F (-15°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

Note: Read and follow component suppliers environmental, health and safety

recommendations prior to preparing this etch solution.

3. Rinse: Rinse panels in clean running tap water.

4. Dry: Air dry 15 minutes; force dry 10 minutes at 190°F (88°C) ± 10°F (5°C).

Plastics/Rubber

1. Wipe with isopropyl alcohol.*

2. Abrade using fine grit abrasives.

3. Wipe with isopropyl alcohol.*

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

follow manufacturer’s precautions and directions for use.

Surface Preparation (continued)

Glass

1. Solvent wipe surface using acetone or methyl ethyl ketone (MEK).*

2. Apply a thin coating (0.0001 in. or less) of primer such as 3M™ Scotch-Weld™

Structural Adhesive Primer EC-3901 to the glass surfaces to be bonded and allow

the primer to dry before bonding.

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

follow manufacturer’s precautions and directions for use.

The following product performance data were obtained in the 3M laboratory under the

conditions specified. The following data show typical results obtained with the 3M™

Scotch-Weld™ Epoxy Adhesive DP100 FR when applied to properly prepared substrates,

cured, and tested according to the specifications indicated. This data was generated using

the 3M™ EPX™ Applicator System equipped with an EPX static mixer, according to

manufacturer’s directions. Thorough manual mixing should afford comparable results.

11 Overlap Shear (ASTM D 1002-64)

Overlap shear (OLS) strengths were measured on 1" wide 1/2" overlap specimens. These bonds were made individually

using 1" x 4" pieces of substrate except for aluminum. Two panels 0.063" thick, 4" x 7" of 2024 T-3 clad aluminum were

bonded and cut into 1" wide samples after 24 hours. The thickness of the bond line was 0.005-0.008". All strengths were

measured at 73°F (23°C) except where noted.

The separation rate of the testing jaws was 0.1" per minute for metals, 2" per minute for plastics. The thickness of the

substrates were: metals, 0.060"; plastics, 0.125".

Storage Store product at 60-80°F (16-27°C) for maximum storage life. Higher temperatures

reduce normal storage life. Lower temperatures may cause increased viscosity of a

temporary nature. Rotate stock on a “first in-first out” basis.
