Premium 3M polyester masking tape with silicone adhesive for high-temperature applications from -60°F to 400°F. Features clean removal, excellent chemical resistance, and translucent blue backing. 0.5 in × 72 yd rolls, 96 per case.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications where thermal resistance and clean removal are critical. This professional-grade tape features a silicone adhesive that provides exceptional bonding to difficult surfaces including silicone-coated substrates, while maintaining flexibility across extreme temperature ranges from -60°F (-50°C) to 400°F (204°C). The translucent blue polyester backing offers excellent tear resistance and easy identification during application, making it ideal for precision masking operations in powder coating, composite bonding, and metal processing environments.
The tape excels in high-temperature powder coat painting applications, providing sharp paint lines and clean one-piece removal without slivering or breaking. Its superior chemical resistance makes it suitable for demanding work conditions including anodization, acid milling, and caustic chemical processes. As a thicker version of the 3M Polyester Tape 8901, model 8902 provides enhanced durability and extended wear life for longer-duration masking operations. The pressure-sensitive silicone adhesive ensures reliable performance under thermal stress, making it the preferred choice for aerospace, automotive, and specialty manufacturing applications.
This industrial-grade tape is commonly used for protective masking during shipping and handling operations, flash breaker applications in metal bonding processes, and permanent splicing of silicone liners, papers, and films subject to elevated temperatures. Each case contains 96 rolls, providing substantial inventory for high-volume production environments. The tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, ensuring compliance with industry standards for masking and surface protection applications.
