Surface Preparation
™
Scotch-Weld
3M™ Scotch-Weld™ Epoxy Adhesive DP920 is designed to be used on oiled metal
surfaces.
Since each oiled metal surface combination may be unique, it is suggested that the
specific oiled metal combination be reviewed prior to use.
Please contact 3M™ Technical Service @ 800-362-3550 for further assistance.
Directions for Use
1. For high strength structural bonds, paint, oxide films, oils, dust, mold release
2. Mixing
3. For maximum bond strength, apply adhesive evenly to both surfaces to be
4. Application to the substrates should be made within 15-20 minutes. Larger
5. Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above
6. Keep parts from moving during cure. Apply contact pressure if necessary.
7. Excess uncured adhesive can be cleaned up with ketone type solvents*.
™
agents and all other surface contaminants must be completely removed. The
amount of surface preparation depends on the required bond strength,
environmental aging resistance desired by user. For suggested surface
preparations on common substrates, see the section on surface preparation.
For Duo-Pak Cartridges
3M™ Scotch-Weld™ Epoxy Adhesive DP920 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 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 typical uncured properties section. Mix approximately 15 seconds
after a uniform color is obtained.

until completely firm. Heat up to 120°F - 150°F (49°C - 66°C) will speed
curing.
Maximum shear strength is obtained with a 3-5 mil bond line.
*Note: When using solvents, extinguish all ignition sources, including pilot
lights, and follow the manufacturer’s precautions and directions for use.
