Product Description
3M™ Scotch-Weld™ Low Odor Acrylic Adhesives are high performance, two-
part acrylic adhesives that offer excellent shear, peel, and impact performance.
These toughened products provide improved adhesion to many plastics and
metals, including those with slightly oily surfaces. These durable products
feature a fast rate of strength build, providing structural strength in minutes.
Their low odor and non-flammability feature also makes them easier to
incorporate into a manufacturing process.
Review UL File QOQW2. MH17478 and Sign Components Manual (SAM) File
E464624 for certification of these adhesive systems in electrical equipment.
DP8810NS Green has been tested for surface flammability, smoke, toxic gas
generation, and caloric content per ASTM E162, ASTM E662, ASTM E1354,
Bombardier SMP 800-C, and Boeing BSS 7239 test methods. DP8805NS
Green and DP8825NS Green should yield similar results.

7. Overlap shear values measured using ASTM D1002; 1 min open time; adhesive allowed to cure for 24 hours at room temperature; 1/2"
overlap; 0.010" bond line thickness; samples pulled at 0.1 in/min for metals and 2 in/min for plastics; all surfaces prepared with light
abrasion and solvent clean; substrates used were 1/16" thick metals and 1/8" thick plastics; failure modes:
AF: adhesive failure CF: cohesive failure SF: substrate failure
Note: Environmental aging tests have shown that these adhesives may accelerate the corrosion of
certain bare metals (such as cold rolled steel, copper, brass, and bronze), leading to low bond strength
values and early bond failure. These adhesives also have relatively low adhesion to low surface energy
plastics (such as polypropylene, polyethylene, TPO, and PTFE). Applications involving any of these
materials should be carefully evaluated by the end user for suitability.
Note: The presence of oxygen inhibits the cure of acrylic structural adhesives. Therefore, any exposed
surfaces of the mixed adhesive will cure much more slowly than adhesive contained within the bond
line. With methyl methacrylate (MMA) acrylic adhesives, any uncured adhesive on the surface flashes
off immediately, leaving a surface that feels dry to the touch. With these low odor acrylic adhesives,
uncured adhesive on exposed surfaces does not evaporate away quickly, leaving a wet film of partially
cured material. For manufacturing processes that need a dry surface quickly, such as for subsequent
sanding or painting operations, consider instead the standard acrylic adhesives (DP8405NS Green,
DP8410NS Green, DP8425NS Green, and Metal Bonder DP8407NS Green).

Note: Fully-cured structural adhesives can withstand short-term incidental contact with almost any
solvent, chemical, or environmental condition. However, long-term continuous exposure of these
Acrylic Adhesives to the following liquids should be avoided:
1. Elevated temperature (>100°F) water
2. Ketone-type solvents (acetone, MEK)
3. Gasoline and similar liquids

Note: The data in this sheet were generated using the 3M™ EPX Applicator System equipped with an
EPX static mixer, according to manufacturer’s directions. Thorough hand-mixing will afford
comparable results.

Directions for Use
1. To obtain the highest strength structural bonds, paint, oxide films, oils, dust, mold
release agents, and all other surface contaminants must be completely removed.
The amount of surface preparation depends on the required bond strength and
environmental aging resistance desired by user. For suggested surface
preparations on common substrates, see the section on surface preparation.
2. Mixing For Duo-Pak Cartridges
Store cartridges with cap end up to allow any air bubbles to rise towards the
tip. To use, simply insert the cartridge into the EPX applicator and start the
plunger into the cylinders using light pressure on the trigger. Then remove
the cap and expel a small amount of adhesive to ensure material flows freely
from both sides of cartridge. For automatic mixing, attach an EPX mixing
nozzle to the cartridge and begin dispensing the adhesive. For hand mixing,
expel the desired amount of adhesive and mix thoroughly. Mix approximately
15 seconds after obtaining a uniform color.
Mixing For Bulk Containers
Mix thoroughly by weight or volume in the proportion specified on the
product label or in the typical uncured properties section. Mix approximately
15 seconds after obtaining a uniform color.
3. Apply adhesive and join surfaces within the open time listed for the specific
product. Larger quantities and/or higher temperatures will reduce this
working time.
4. The adhesive and all materials should be at 60°F (16°C) or above prior to
assembly. Allow adhesive to cure at 60°F (16°C) or above until completely
firm. Applying heat up to 150°F (66°C) will increase cure speed.
5. Keep parts from moving during cure. Apply contact pressure or fixture in
place if necessary. Optimum bond line thickness ranges from 0.005 to 0.020
inch; shear strength will be maximized with thinner bond lines, while peel
strength reaches a maximum with thicker bond lines.
6. 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.

remove the paint layer or coating down to bare steel.
3. Wipe again with clean cloth and pure isopropyl alcohol to remove
loose particles.*
Aluminum/stainless steel:
1. Wipe surface free of dust and dirt with clean cloth and pure acetone.*
2. Sandblast or lightly abrade using clean fine grit abrasives.
3. Wipe again with clean cloth and pure acetone to remove loose particles.*
Plastics:
1. Wipe surface free of dust and dirt with clean cloth and pure
isopropyl alcohol.*
2. Lightly abrade using fine grit abrasives.
3. Wipe again with clean cloth and pure isopropyl alcohol to remove
loose particles.*
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the
manufacturer’s precautions and directions for use.
