toughened structural adhesives with less odor than most acrylic adhesives. These
adhesives have excellent shear and peel strength along with good impact resistance
and durability. They can quickly bond to most metals, ceramics, rubbers, plastics
and wood with minimal surface preparation.
Features • Tough, durable bonds • Lo w-odor acrylic adhesive
• Minimal surface prep • 10 minute worklife
• 10 minute time to handling strength • 1:1 mix ratio
• Bonds stainless steel • Excellent shear and peel strength

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,
allo wed 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 adhesi v e to clean, dry substrates, which are free of paint, oxide f ilms, oils, dust,
mold release agents and all other surface contaminants. See the Surface Preparation
section for specific substrate preparation method.
50 ml cartridge:.
Place Duo-Pak cartridge in 3M™ EPX™ Applicator. Remove cap. Dispense and
discard a small amount of adhesi v e to assure even ratio and free flow. Clear orif ice if
necessary. Attach mixing nozzle. Apply adhesive to clean surfaces, join parts, secure
until adhesi v e sets.
200/400 ml cartridge
While holding Duo-Pak cartridge in an upright position, remo ve and discard the insert
from the cartridge by unscre wing plastic nut and remo ving metal w asher. Place
cartridge in a 1:1 200/400 ml EPX applicator. Dispense and discard a small amount of
adhesi v e to ensure even ratio and free flow. Attach mixing and nozzle and secure with
plastic retaining nut. Apply adhesi v e to clean surf aces, join parts, secure until
adhesi v e sets.
Clean-up:
Excess adhesi v e can be removed with solvent such as MEK.*Edge tack on a finished
part or bond line can be remov ed with isoprop yl alcohol.*
*Note: When using solvents, e xtinguish 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 surf ace 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 follo wing cleaning methods are suggested for common surfaces.
Steel and Aluminum
1) Wipe free of dust with oil-free solvent such as acetone or isoprop yl
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) Remo ve 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.
