  • Best Practices for 3M SJ5508

    *See Terms of Use Below

    1. 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.

    2. Application

      Apply firm pressure to help increase the cold flow and contact of the adhesive with the substrate

    3. Curing

      Allow time (dwell) to increase the surface contact and adhesion (see illustrations below).
