Surface Preparation
™
Scotch-Weld
For smaller or intermittent applications, the 3M™ EPX™ Applicator is a convenient
method of application.
For larger applications these products may be applied by use of flow equipment.
Two part meter/mixing/proportioning/dispensing equipment is available for
intermittent or production line use. These systems may be desirable because of their
variable shot size and flow rate characteristics and are adaptable to many applications.
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 directly depends on the required bond strength and the
environmental aging resistance desired by the user.
The following cleaning methods are suggested for common surfaces:
Steel:
1. Wipe free of dust with oil-free solvent such as acetone, isopropyl or alcohol
2. Sandblast or abrade using clean fine grit abrasives.
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.
Aluminum:
1. Alkaline Degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F (87°C) ±
2. Acid Etch: Place panels in the following solution for 10 minutes at 150°F (65°C)
3. Rinse: Rinse panels in clear running tap water.
4. Dry: Air dry 15 minutes; force dry 10 minutes at 150°F (65°C) ± 10°F.
5. If primer is to be used, it should be applied within 4 hours after surface preparation.
Plastics/Rubber:
1. Wipe with isopropyl alcohol.*
2. Abrade using fine grit abrasives.
3. Wipe with isopropyl alcohol.*
Glass:
1. Solvent wipe surface using acetone or MEK.*
2. Apply a thin coating (0.0001 in. or less) of 3M™ Scotch-Weld™ Metal Primer
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and
solvents.*
10°F for 10-20 minutes. Rinse immediately in large quantities of cold running water. *
± 5°F.*
EC3901 or equivalent to the glass surfaces to be bonded and allow the primer to
dry before bonding.
