3M 8991 Polyester Tape

3M™ Polyester Tape 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. Polyester films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility. Blue color makes tape placement obvious for both application and removal. Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing, and adhesive transfer. 8991L is linered version.

Applications: masking for powdercoat painting, flashbreaker tape when pulling through cured coating, holding and splicing difficult to stick to surfaces, holding parts or sealing vaccum bags during processing
