Thin and conformable, our 3M polyester tape 8991 is a general purpose tape that excels in high temperature masking operations such as powder coat painting. Coated with a silicone adhesive, this tape bonds to a variety of difficult surfaces. It is chemical resistant and performs under a wide range of temperatures and environments. 3M polyester tape 8991 is available in a variety of sizes. 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 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 deg F/204 deg C and adheres well to tough to stick to surfaces like silicone liners and fixtures coated with mold release. When you need a strong tape that will deliver reliable masking and sharp, clean paint lines in high temperatures, our polyester tape 8991 is an exceptional choice. For optimal results for many applications, 3M polyester tape 8991 provides the strength, durability and clean finish you've come to expect from 3M tapes.
