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.: Wipe free of dust with oil-free solvent such as acetone or isopropyl alcohol.

Sandblast or abrade using clean fine grit abrasives (180 grit or finer).

Wipe again with solvent to remove loose particles.

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.

Wipe with isopropyl alcohol.

Abrade using fine grit abrasives (180 grit or finer).

Remove residue by wiping again with isopropyl alcohol.

Solvent wipe surface using acetone.

Apply a thin coating (0.0001" or less) of 3M™ Scotch-Weld™ EC-3901 Primer to the glass surfaces to be bonded and allow the primer to dry a minimum of 30 minutes at 75°F (24°C) before bonding for maximum adhesion.

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.
Application

Directions for use: Apply adhesive to clean, dry substrates, which are free of paint, oxide films, oils, dust, mold release agents and all other surface contaminants. See the Surface Preparation section for specific substrate preparation method.
Clean-Up

Excess adhesive can be removed with solvent such as 3M™ Scotch-Grip™ Solvent No. 3 or equivalent. Edge tack on a finished part or bond line can be removed with isopropyl alcohol*.

*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
