Premium high-temperature polyester masking tape with silicone adhesive for extreme temperature applications ranging from -60°F to 400°F, featuring clean removal, excellent chemical resistance, and superior durability for industrial powder coating and manufacturing processes.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications. This durable polyester tape features a silicone adhesive that provides exceptional performance in extreme temperature environments ranging from -60°F (-50°C) to 400°F (204°C). The tape excels in high-temperature masking operations such as powder coat painting, delivering clean removal and sharp paint lines without slivering or breaking. With its translucent blue backing, the tape offers easy identification and positioning during application, while maintaining excellent tear resistance and durability.
This thicker version of 3M Polyester Tape 8901 is specifically designed for industrial/occupational use in demanding conditions where chemical resistance and thermal stability are critical. The silicone-based adhesive bonds effectively to difficult surfaces including silicone-coated materials, while the polyester backing provides superior chemical resistance. The tape performs exceptionally well in various industrial processes including anodization, chemical milling, composite bonding operations, and permanent splicing of silicone liners, papers, and films subject to elevated temperatures.
The 3M Polyester Tape 8902 is available in 6-inch width with 72-yard length per roll, 3.4 mil thickness, and is sold in cases of 8 rolls. This professional-grade tape meets rigorous ASTM standards (ASTM D3330, ASTM D3652, ASTM D3759) and demonstrates 140% elongation at break for superior flexibility. Whether used for masking metal surfaces in acid or caustic chemical milling baths, protecting parts during shipping and handling, or serving as a flash breaker in metal bonding processes, this tape delivers consistent, reliable performance in the most challenging industrial environments.
