  • Best Practices for 3M 4014

    *See Terms of Use Below

    1. Surface Preparation

      Best results are obtained when applied at temperatures above 50°F (10°C) on a clean, dry surface (free of oil, wax, dust, rust, etc.) and the bond is continuous (void-free) throughout the interface between 3M damping aluminum foam sheet 4014 and the structure.

      Clean metal surface of structure with appropriate solvent for removing any surface contaminants such as processing oils or waxes.

      Note: When using solvents, be sure to extinguish ignitions sources and follow the manufacturer’s precautions and directions for use when handling such materials.

      Wipe the clean surface of the structure to complete dryness with a clean, dry lint free cloth.

      Note: Steps 1 and 2 should be repeated until the used drying cloth is clean (no more residue appears on the cloth after wiping).

    2. Application

      Remove the protection liner.

      Place one edge on the surface of the structure and press into place with finger pressure. Lower the rest of the foam piece into place while applying finger pressure on the bond line as it progresses across the surface of the structure. This method of application will minimize voids in the pressure sensitive bond.
