Industrial-grade polyester masking tape with silicone adhesive for high-temperature applications ranging from -60°F to 400°F. Features clean removal, excellent thermal and chemical resistance, and superior durability for powder coating, composite bonding, and metal processing.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications requiring exceptional thermal and chemical resistance. This translucent blue polyester tape features a silicone adhesive that provides clean removal and superior performance across a wide temperature range from -60°F (-50°C) to 400°F (204°C). The tape excels in powder coating operations, composite bonding, metal chemical milling, and other high-temperature masking applications where precision and reliability are critical.
With a thickness of 3.4 mil and a width of 24 inches, this industrial-grade tape delivers durability and longevity in the most challenging work environments. The silicone adhesive formulation ensures excellent adhesion to difficult surfaces including silicone-coated materials, while maintaining the ability to remove cleanly and in one piece without slivering or breaking. The tear-resistant polyester backing provides easy identification and positioning during application, making it ideal for professional industrial use.
This tape is specifically designed as a thicker, more durable version of the 3M Polyester Tape 8901, offering enhanced performance for applications requiring extended wear and superior protection. Whether used for flash breaker in metal bonding processes, protective tape during shipping and handling, or permanent splicing operations on silicone liners and films, the 3M Polyester Tape 8902 delivers consistent, reliable results in the most demanding conditions.
