  • Best Practices for 3M AF111

    *See Terms of Use Below

    1. Surface Preparation

      A thoroughly cleaned, dry, grease-free surface is essential for maximum performance. Cleaning methods which will produce a break-free water film on metal surfaces are generally satisfactory.

    2. Curing

      The suggested curing condition for Bonding Film AF111 is 60 minutes at 250°F (121°C). The adhesive may be cured either under pressure or in a vacuum bag

      During cure, pressure is required to keep parts in alignment and in intimate contact. A minimum of 20 psi is suggested, but higher psi is acceptable if resultant flow during cure is not excessive.

    3. Clean-Up

      Uncured 3M™ Bonding Film AF111 can be removed using acetone, MEK or 3M™ Citrus Base Cleaner.

      Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
