Shelf Life Details Store product at 60-80°F (15-26°C) for maximum storage life. Higher temperatures reduce normal storage life. Lower temperatures cause increased viscosity of a temporary nature. Rotate stock on a “first-in first-out” basis. When stored at the recommended conditions in original, unopened containers, this product has a shelf life of 15 months.

Best Practices for 3M 2141
-
Surface Preparation
Surfaces must be clean, dry and dust free. Wiping with a solvent such as methyl ethyl ketone (MEK) will aid in removing oil and dirt.*
*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
-
Application
For best results the temperature of the adhesive and the surfaces being bonded should be at least 65°F (18°C).
Stir or agitate well before using.
Porous Surface(s): Apply a uniform generous brush coat of adhesive to one or both surfaces. Highest strengths are obtained when both surfaces are coated. Highly absorbent materials may require two coats.
Non-Porous Surface(s): Brush an even coat of adhesive on both surfaces. Press surfaces together firmly to ensure contact.
-
Curing
When applying adhesive to only one surface, the bond must be made immediately, while the adhesive is wet. When applying adhesive to both surfaces, allow the adhesive to dry until tacky, but does not transfer to knuckle when touched (typically 5-10 minutes, depending on temperature, humidity, etc.).
After drying, you have up to 15 minutes to make the bond. Press surfaces together firmly to ensure contact.
-
Clean-Up
Excess adhesive may be removed with a solvent such as 3M™ Scotch-Weld™ Solvent No. 2, methyl ethyl ketone (MEK), or 3M™ Citrus Base Cleaner.*
*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
