Test Methods and
Footnotes
1) Viscosity obtained by Brookfield, DV-II, #7 Spindle, 20 rpm at 75°F (24°C).
2) Overlap Shear Test Method: overlap shear test for adhesion determined in
accordance to ASTM D1002-72, sample dimensions were 1" x 4" x 1/8", with a
1/2 square inch area of overlap, bonded to themselves unless otherwise noted,
allowed to cure for at least 6 hours at 75°F (24°C) before testing. Data were
collected using a Sintech 5GL Mechanical Tester with a 2000# or 5000# load
cell. Test rate was 0.1"/minute. Strength determined at 75°F (24°C) unless
otherwise noted.
3) Peel tests (ASTM D1876-61T) on FPL etched, 0.032” gauge aluminum, with a
.017" bondline thickness. Jaw separation rate 20"/min. All bonds were allowed to
cure for at least 6 hours at 75°F (24°C) before testing.
4) Environmental tests were conducted by immersing bonded coupons prepared in
accordance to description in footnote 2.

Handling/Curing
Information
Directions for use:
Apply adhesive to clean, dry substrates, which are free of paint, oxide films, oils, dust,
mold release agents and all other surface contaminants. See the Surface Preparation
section for specific substrate preparation method.
48.5 ml cartridge:
Place Duo-Pak cartridge in 3M™ EPX Applicator. Remove cap. Dispense and
discard a small amount of adhesive to assure even ratio and free flow. Clear orifice if
necessary. Attach mixing nozzle. Apply adhesive to clean surfaces, join parts, secure
until adhesive sets.
200/400 ml cartridge:
While holding Duo-Pak cartridge in an upright position, remove and discard the insert
from the cartridge by unscrewing plastic nut and removing metal washer. Place
cartridge in a 1:1 200/400 ml EPX applicator. Dispense and discard a small amount of
adhesive to ensure even ratio and free flow. Attach mixing and nozzle and secure with
plastic retaining nut. Apply adhesive to clean surfaces, join parts, secure until adhesive
sets.
Clean-up:
Excess adhesive can be removed with solvent such as MEK*. Edge tack on a finished
part or bond line can be removed with isopropyl alcohol.*
*Note: When using solvents, extinguish all ignition sources and follow the
manufacturer’s precautions and directions for use.
Heat Cure:
Full cure can be attained by raising the bondline temperature to 120°F (49°C) for
30 minutes or to 150°F (66°C) for 10 minutes.

Surface Preparation
3M™ Scotch-Weld™ Low Odor Acrylic Adhesives can bond oily metal, plastic and
other substrates with very little surface preparation. However, for the most consistent
results and environmental resistance, all substrates should be clean, dry and free of
paint, oxide films, dust, mold release agents and all other surface contaminants. The
amount of surface preparation directly depends on the bond strength and
environmental resistance desired by the user.
The following cleaning methods are suggested for common surfaces.
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 (180 grit or finer).
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 (or see instructions pertinent to a specific primer).
Note: Aluminum may also be acid etched. Follow the manufacturer’s
precautions and directions for this procedure.
Plastic/Rubber
1) Wipe with isopropyl alcohol.*
2) Abrade using fine grit abrasives (180 grit or finer).
3) Remove residue by wiping again with isopropyl alcohol.*
*Note: When using solvents, extinguish all ignition sources and follow the
manufacturer’s precautions and directions for use.
