Premium high-temperature polyester masking tape with silicone adhesive, operating from -60°F to 400°F, offering clean removal and excellent chemical resistance for industrial applications.
The 3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications. This advanced polyester tape features a silicone adhesive that delivers clean, one-piece removal from most surfaces without slivering or breaking. With a translucent blue backing that provides excellent tear resistance and easy identification, this tape is specifically designed for high-temperature masking operations such as powder coat painting and other demanding work conditions.
This tape excels in performance across a wide range of temperatures, operating reliably from -60°F (-50°C) to 400°F (204°C), making it ideal for extreme thermal environments. The polyester film backing offers exceptional thermal and chemical resistance while maintaining superior flexibility, ensuring reliable performance in anodization, chemical milling, and other aggressive chemical processes. As a thicker version of the 3M Polyester Tape 8901, this tape provides enhanced durability and extended wear characteristics for prolonged masking applications.
The 3M Polyester Tape 8902 is commonly used for protective applications during shipping and handling operations, flash breaking in metal bonding processes, splicing of silicone liners and films, and holding parts during composite bonding operations. With its silicone pressure-sensitive adhesive and excellent chemical resistance, this industrial-grade tape is an essential solution for manufacturing facilities, automotive shops, aerospace applications, and any operation requiring reliable high-temperature masking performance.
