Description

Masking tape 3M 8991 is a blue polyester tape with a silicone adhesive. It can be used in a large variety of high temperature applications including powdercoat masking, flashbreaker, and bag sealing applications. Additional applications include, splicing, tabbing, or roll closing silicone treated liners or materials Features
  • Polyester films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility.
  • Blue color makes tape placement obvious for both application and removal.
  • Thin backing leaves a sharp paint line and some conformability.
  • Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing, and adhesive transfer.
  • Silicone adhesives adhere well to tough-to-stick-to surfaces like silicone liners and fixtures coated with mold release.
  • Silicone adhesive removes cleanly from many surfaces.
  • Linered version available for die-cuts.
Application Ideas
  • Masking for powdercoat painting.
  • Flashbreaker tape when pulling through cured coating such as epoxies.
  • Holding and splicing difficult to stick to surfaces such as silicone liner.
  • Holding parts or sealing vacuum bags during processing.
