3M™ 8991 Polyester Tape is a blue polyester tape with a silicone adhesive lining. This is an excellent tape for applications that require high temperature resistance. We recommend this polyester tape for powder coat masking, bag sealing, and any splicing, tabbing, or roll closing on various materials.
The polyester make up of the 3M™ 8991 tape allows it to withstand abrasion and chemical spills whilst maintaining flexibility and strength. Strong silicone adhesive backing makes it a better choice for working with tough-to-stick to surfaces than rubber and acrylic adhesives which require uniform and conventional surfaces. The blue colouring of the tape makes it easy to spot, it can be used a marking and placement tape as it is easy to see and can be easily removed without leaving adhesive residue behind. We recommend using this tape for projects requiring sharp lines and some conformability.
Suitable for masking for powder coat painting, flash breaker tape when pulling through cured coating such as epoxies. Also suitable for holding and splicing difficult to stick to surfaces, as well as holding parts or sealing vacuum bags during processing.
