3M™ Acrylic Foam Tape (AFT) GT7108 is a gray, acrylic foam tape designed for the attachment of emblems, nameplates, moldings, step pads and other automotive trim. The acrylic foam core has unique viscoelastic properties that allow it to elongate and relax when put under load, thereby minimizing stress on the adhesive bondline. It exhibits very good adhesion to traditional paints.
FEATURES
- Demonstrates excellent conformability and wet out on a range of automotive applications
- Maintains adhesion during the shrinkage and elongation of the part caused by temperature changes, while simultaneously maintaining good stress relaxation properties
- Provides very good final adhesion and peel strength
- Performs well in a wide range of weather, solvent, and temperature conditions
APPLICATIONS
- Deck Lid Appliques
- Thin or Flexible Nameplates
- Appliques
- Ground Effects
- Rocker Panel Moldings and Cladding
- Trim Moldings
