Surface Preparation 3M™ Scotch-Weld™ Low-Odour 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.
