For high strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must me completely removed. The amount of surface preparation depends on the required bond strength, environmental aging resistance desired by the user.
The following cleaning methods are suggested for common surfaces: Steel: Wipe free of dust with oil-free solvent such as acetone or isopropyl alcohol solvents.
Sandblast or abrade using clean fine grit abrasives.
Wipe again with solvent to remove loose particles
If a primer is used, it should be applied within 4 hours after surface preparation. If 3M™ Scotch-Weld™ Structural Adhesive Primer EC1945 B/A is used, apply a thin coating (0.5 mils or 0.013 mm) on the metal surfaces to be bonded, air dry for 10 minutes, then cure for 30 minutes at 180°F (82°C) prior to bonding.
Aluminum: Alkaline degrease: Oakite 164 solution (9-11 oz./gallon water) at 190°F ± 10°F (88°C ± 5°C) for 10-20 minutes. Rinse immediately in large quantities of cold running water.
Acid etch: place panels in the following solution for 10 minutes at 150°F ± 5°F (66°C ± 2°C) Sodium dichromate 4.1 - 4.9 oz./gallon, Sulfuric acid, 66°Be 38.5 - 41.5 oz./gallon, 2024-T3 aluminum (dissolved) 0.2 oz./gallon minimum Tap water as needed for balance
Rinse: rinse panels in clear running tap water
Dry: air dry for 15 minutes, force dry for 10 minutes at 190°F ± 10°F (88°C ± 5°C).
If primer is to be used, it should be applied within 4 hours after surface preparation.
Plastics/Rubber: Wipe with isopropyl alcohol .
Abrade using fine grit abrasives.
Wipe with isopropyl alcohol .
Glass:Solvent wipe surface using acetone or MEK .
Apply a thin coating (0.0001 in. or less) of 3M™ Scotch-Weld™ Metal Primer EC3901 to the glass surfaces to be bonded and allow the primer to dry before bonding.
For Duo-Pak Cartridges: 3M™ Scotch-Weld™ Acrylic Adhesives DP807, DP812 and DP825 are 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.
Once 3M™ Scotch-Weld™ Acrylic Adhesive has been applied to a surface, it is best to join the two mating surfaces together as soon as possible or within the applied open time. The reason for this is that beyond the applied open time, Scotch-Weld acrylic adhesive may begin to form a thin “skin” over the exposed surface. If left exposed long enough, a thick enough “skin” may form which will inhibit the proper wetting needed to achieve maximum strength.

Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until completely firm. Heat up to 120°F - 150°F (49°C - 66°C) will also speed curing. Scotch-Weld acrylic adhesives will fully cure in 24 hours @ 75°F (24°C)
Keep parts from moving during cure. Apply contact pressure if necessary. Maximum shear strength is obtained with a 3-5 mil bond line
Excess uncured adhesive can be cleaned up with ketone type solvents.
When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use.

| 4,000 psi | 24°C | Etched Aluminum | 60 min | 23°C | Overlap Shear (ASTM D-1002-64, 3M Test Method C-236) strength was measured on 1" wide x 1/2" overlap specimen. These bonds were made individually using 1" x 4" coupons. The thickness of the adhesive bond line was approximately 0.005". All strengths were measured at 73°F (23°C) except when noted, and samples were allowed to cure at 75°F (24°C) and approximately 50% RH for 1 week before immersed. The separation rate of the testing jaws was 0.1 inch per minute. |
