Selecting the Tape Construction

The next step is to define the tape construction. You must choose between a transfer tape and a double coated construction. Transfer tapes are less costly and more conformable. Double coated tapes have higher strength and stiffness, and can be used as a gap-filling or barrier. In addition, double coated tapes are easier to slit. When cutting through the adhesive, there is always a risk of edge picking when using a transfer tape. To determine the most appropriate carrier, use the table under “carrier” (Click to proceed to Carrier).

Selecting the Liner

Finally, to select the liner, use the selection chart under “liner” (Click to proceed to Liners).

Application Conditions

When applying PSA tapes, keep the following conditions in mind:

  • Bonding surface must be clean, dry and free of all grease and oil contaminates
  • PSAs require a minimum of 20-40 psi to secure most bonds
  • Minimum application temperature above 50°F
  • Heat lamination improves surface contact area and decreases wet out time
  • Adhesion builds up to reach maximum adhesion level up to 72 hours after application
