Best Practices for 3M 826 Scotch-Weld Nitrile Plastic Adhesive
-
Surface Preparation
Surfaces must be clean, dry and dust free. Wiping thoroughly with 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.
-
Curing
Drying time depends on temperature, humidity, air movement, and porosity of the materials bonded. Typically, drying times of 5 to 10 minutes can be expected.
-
Clean-Up
Cleanup: Excess adhesive may be removed with methyl ethyl ketone (MEK)* or acetone*, preferably while still wet.
*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
