Meets the Demands that Come with High-Temperature Applications
We engineered 3M™ Polyester Tape 8991 as a pressure-sensitive silicone adhesive that grabs on contact and offers high heat resistance, reducing failure due to softening, oozing and adhesive transfer. This high-temperature tape is also designed with a thin polyester backing that resists shrinking, curling, tearing and edge lifting, offering reliable masking and consistent results. With a 1.0 mil polyester backing and 1.4 mil silicone adhesive, this tape features sharp, clean paint lines and provides excellent thermal, abrasion and chemical resistance while maintaining flexibility. In addition, 3M™ Polyester Tape 8991 removes without leaving behind adhesive residue, for a clean finish. Our Polyester Tape 8991 performs up to 400°F/204°C and adheres well to tough-to-stick-to surfaces like silicone liners and fixtures coated with mold release.
