Best Practices for 3M Scotch-Weld Epoxy Adhesive DP100 Plus Clear
-
Surface Preparation
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 directly depends on the required bond strength and the environmental aging resistance desired by 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 hour safter surface preparation
1. 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
2. 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 to balance
3. Rinse: Rinse panels in clear running tap water.
4. Dry: Air dry 15 minutes
force dry 10 minutes at 190°F ± 10°F (88°C ± 5°C).
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 fiie grit abrasives.
3. Wipe with isopropyl alcohol.*
Glass:
1. Solvent wipe surface using acetone or MEK.*
-
Application
For small 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/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.
-
Mixing
If automatic mixing of Part A and Part B is desired, attach the EPX applicator 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 uniform color is
Mix thoroughly by weight or volume in the proportions specified in the typical uncured properties section. Mix approximately 15 seconds after uniform color is obtained.
-
Clean-Up
Excess uncured adhesive can be cleaned up with methyl ethyl ketone (MEK).*
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.
