3M™ 1146 Tape is a 6.5 mil polyester film/glass filament tape coated with a thermosetting, pressure-sensitive rubber adhesive.

FEATURES 

  • UL Recognized, Class B (130˚C)
  • High breaking strength
  • Suitable for heavy duty use
  • For maximum solvent resistance and holding properties, the tape should be thermoset at one of the following cycles:

          1 hour @ 150˚C (300˚F)

          2 hours @ 135˚C (275˚F)

          3 hours @ 120˚C (250˚F)

APPLICATIONS 

3M 1146 tape is especially suited for heavy duty equipment applications, bundling armature coils, anchoring, lead holding of heavy gauge wires in transformers, coils and electric motors.
