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.
