Surfaces must be clean, dry and dust free. Wiping with solvent such as 3M™ Scotch-Weld™ No. 3 or methyl ethyl ketone (MEK)* will aid in removing oil and dirt. Plastic surfaces may be cleaned with isopropyl alcohol.*
*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
For best results, the temperature of the adhesive and the surfaces being bonded should be at least 65°F (18°C). Spray, brush, roll or knife coat a smooth, uniform coat of adhesive to the least porous surface. Thickness of the adhesive will depend upon the surfaces being bonded and stress requirements and should be determined by the user. Porous or rough surfaces generally require more adhesive than smooth surfaces.
This will depend on the adhesive film thickness and drying temperature and should be determined by the user. Infrared heat may be used to speed up the drying process, if necessary. Generally, when the adhesive film has changed from an opaque, milky appearance to a clear or transparent and odorless state, drying can be considered complete. In order to maintain long term pressure sensitivity, the dry adhesive film must be kept free of dust or other contaminants through the use of a protective release liner. Bond surfaces together using firm pressure. A 3-inch wide (maximum) rubber roller (J-roller) is recommended. For maximum bond performance, the use of a nip-roll or rotary press is preferred. Bonding while one or both surfaces are warm will also help improve bond results.
Liquid adhesive can be removed from tools and equipment by flushing with large amounts of water. The addition of liquid soap and warm water will aid in cleanup. Dried adhesive may be removed with a solvent such as 3M™ Scotch-Weld™ Solvent No. 3 or methyl ethyl ketone.*
*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
