Best Practices for 3M Industrial Adhesive 4550
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, including pilot lights, and follow manufacturer’s precautions and directions for use.
Spray a uniform line of adhesive down center of bag. Bags can be palletized immediately or within 5 minutes depending upon temperature, humidity and air movement. Best results are obtained if the bags are palletized when the adhesive is aggressively tacky.
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): Brush, spray, flow or roll a uniform coat on the least porous surface to be bonded. Bond immediately, applying pressure to ensure contact. Non-Porous Surface(s) (or for higher immediate strength): Apply a uniform light coat on each surface. Allow the adhesive to dry until it is tacky. Then apply sufficient pressure to ensure intimate contact.
Palletized bags may be handled immediately. Strength of bond increases over a period of 24 hours.
Excess adhesive may be removed with a solvent such as 3M™ Scotch-Grip™ Solvent No. 2.
*Note: When using solvents, be sure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use when handling such materials.
