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™ DP-100 and DP-100 NS Adhesives are supplied 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 colour 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 @ 24°C [75°F]). 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 16°C (60°F) or above until

completely firm. Heat, up to 93°C (200°F), will speed curing. These products will

fully cure in 24-48 hours @ 24°C (75°F).

7. Keep parts from moving during cure. Contact pressure is necessary. Maximum shear

strength is obtained with a 3-5 mil bondline.

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.
