• Description for 3M 9712

    An isotropically conductive pressure sensitive tape. It conducts electricity through the thickness (Z-axis) and in the plane of the adhesive (X, Y planes) and is ideal for EMI/RFI shield and EMI/RFI gasket attachment to metal surfaces.

  • Best Practices for 3M 9712

    *See Terms of Use Below

    1. Surface Preparation

      To obtain maximum adhesion, the bonding surfaces must be clean and dry. Isopropyl alcohol is recommended as a cleaning solvent.

      Electrical performance is dependent upon the nature of the metal and its surface. Most metal surfaces give enhanced electrical performance with tape 9712 when the surface has been lightly abraded. Scotch-BriteTM pads are recommended for preparing the metal surface.

      The surfaces should be cleaned again before applying a new piece of 3M tape 9712. The force required to separate the parts and/or remove the adhesive can be reduced by softening the adhesive by heating to 158°F -212°F (70°C - 100°C) or using solvents such as acetone.

      Note Carefully read and follow the manufacturer's precautions and directions for use when handling cleaning solvents.

    2. Application

      Bond Strength is dependent upon the amount of adhesive-to-surface contact developed. This wetted area can be increased by applying 3MTM XYZ-Axis Electrically Conductive Tape 9712 firmly with a roller or finger pressure to exclude air entrapment. Adhesion is optimized when the substrates are flat or conformable substrates. Adhesion increases after application, up to 24 hours later, due to increased wetting by the tape.

      Tape application below 50°F (10°C) is not recommended because the adhesive will be too firm to wet the substrates, resulting in low adhesion. Warming the substrates to 100°F (38°C) facilitates adhesion. Once properly applied, low temperature holding power is generally satisfactory.

    3. Removal

      3M tape 9712 can be removed by separating the parts using torque for rigid parts or peel for flexible ones. Remove the adhesive by pulling off as much as possible by application of 3MTM packaging Tape over the residual adhesive followed by removal of packaging tape.

      Note Carefully read and follow the manufacturer's precautions and directions for use when handling cleaning solvents.
