Handling/Curing

Information

Directions For Use

1. For high strength structural bonds, paints, 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 section on surface preparation.

2. Use gloves to minimize skin contact. Do not use solvents for cleaning hands.

3. Mixing.

For Duo Pak Cartridges

3M™ Scotch-Weld™ Epoxy Adhesives DP125 Translucent and Gray 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 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

obtained.

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 made within 20 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

cure in 7 days @ 75°F (24°C).

7. Keep parts from moving during cure. Contact pressure 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, including pilot lights, and

follow manufacturer’s precautions and directions for use.

Adhesive Coverage (typical): A 0.005 in. thick bondline will yield a coverage of

320 sq. ft./gallon.
