3M 1099L

Surface Preparation

Remove all dust, dirt, oil, grease, wax, loose paint, etc. Wiping with methyl ethyl ketone (MEK)* or 3M™ Citrus Base Cleaner* will aid in preparing the surface for bonding.

*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.

Application

For best results, the temperature of the adhesive and surfaces should be at least 65°F (18°C).

Stir well before using.

Porous Surface(s): Brush, flow or spray a thin, even coat of adhesive to one or both surfaces. Coating both surfaces is preferred since it gives greater strength and permits longer open time before bonding. Very absorbent materials may require more than one coat. Bond while adhesive is still wet or aggressively tacky. Join surfaces with firm pressure.

Non-Porous Surface(s): Brush, flow or spray a thin, even coat of adhesive to both surfaces. Allow adhesive to dry until tacky. Join surfaces with firm pressure.

Curing

Drying time depends on temperature humidity, air movement, and porosity of the materials bonded. Greater immediate strength may be obtained by heat or solvent reactivation.

3M™ Scotch-Weld™ Nitrile High Performance Plastic Adhesive 1099 and 1099-L may be heat cured to obtain superior properties. Cure assembled parts at time and temperature listed using 100 psi pressure on the bond line.

Clean-Up

Excess adhesive may be removed with methyl ethyl ketone (MEK)* or acetone,* preferably while adhesive is still wet.

*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.
