Best Practices for 3M SJ5508
-
Surface Preparation
To obtain maximum adhesion, surfaces must be unified, dry, and free of contaminants. Surface contact is essential to adhesive performance. To maximize contact on a substrate: Clean surfaces with low strength solvent such as isopropyl alcohol (rubbing alcohol) or heptane.
Note: Be sure to follow the manufacturer’s precautions and directions for use when using solvents.
-
Application
Apply firm pressure to help increase the cold flow and contact of the adhesive with the substrate
-
Curing
Allow time (dwell) to increase the surface contact and adhesion (see illustrations below).
