Premium polyester masking tape with silicone adhesive for high-temperature applications from -60°F to 400°F, offering clean removal and excellent thermal/chemical resistance
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications including powder coating, chemical processing, and aerospace manufacturing. This thicker polyester tape features a silicone adhesive that provides exceptional bonding to difficult surfaces including silicone-coated materials. The translucent blue backing offers excellent visibility for precise positioning and identification during application.
Designed to perform reliably across an extreme temperature range from -60°F (-50°C) to 400°F (204°C), this tape excels in high-temperature masking operations such as powder coat painting where clean, sharp paint lines are critical. The polyester film backing delivers outstanding thermal and chemical resistance while maintaining superior flexibility during application and removal. The silicone adhesive formulation ensures clean, one-piece removal from most surfaces without slivering, breaking, or leaving residue, making it ideal for precision masking applications.
The 8902 represents a thicker, more durable version of the 3M Polyester Tape 8901, providing enhanced durability and extended wear life in demanding conditions. With its tear-resistant translucent blue backing and pressure-sensitive silicone adhesive, this tape is commonly used for protective applications during shipping and handling, splicing operations on silicone liners and films, holding parts during composite bonding, and serving as a flash breaker in metal bonding processes. Suitable for industrial and occupational use only, this tape meets rigorous ASTM specifications and is backed by 3M's reputation for quality and innovation.
