Handling/Curing
Information
1. For optimum 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. For specific surface preparations on
common substrates, see the following section on Surface Preparation.
2. Use gloves to minimize skin contact with adhesive.
3. These products consist of two parts.
Mixing and Applying
For Duo-Pak Cartridges - 50 ml
3M™ Scotch-Weld™ DP100 and DP100 NS Adhesives are suppled in a dual syringe
plastic Duo-Pak cartridge as part of the 3M™ Scotch-Weld™ 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 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 uniform color is obtained.
For Duo-Pak Cartridges - 200/400 ml
Directions for Use: While holding cartridge in an upright position, remove insert from
Duo-Pak cartridge by unscrewing plastic nut. Detach metal removal disc from insert to
free plastic nut for nozzle attachment. Clear orifices if necessary. Attach mixing nozzle
and secure with plastic nut. Place cartridge into EPX Applicator. Dispense a small
quantity of adhesive to assure both components are dispensing equally. Apply adhesive
to clean surfaces, join parts, secure until set up (20 minutes @ 75°F [24°C]). Leave
nozzle attached to store. Replace nozzle after storage.
For Bulk Containers
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.
4. For maximum bond strength apply adhesive evenly to both surfaces to be joined.
5. Application to the substrates should be make within 5 minutes. Larger quantities
and/or higher temperatures will reduce this working time.
6. Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until
completely firm. Heat, up to 200°F (93°C), will speed curing. These products will
fully cure in 24-48 hours @ 75°F (24°C).
7. Keep parts from moving during cure. Contact pressure is necessary. Maximum shear
strength is obtained with a 3-5 mil bond line.
8. Excess uncured adhesive can be cleaned up with ketone type solvents.*
*Note: When using solvents, extinguish all ignition sources and follow the
manufacturer’s precautions and directions for use.
Adhesive Coverage: A 0.005 in. thick bondline will typically yield a coverage of
320 sq. ft./gallon.
