Premium high-temperature polyester masking tape with silicone adhesive, rated -60°F to 400°F, ideal for powder coating and industrial applications requiring clean removal and thermal resistance.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications where extreme temperature resistance and clean removal are critical. This blue translucent polyester tape features a silicone-based adhesive that maintains excellent adhesion across a wide temperature range from -60°F (-50°C) to 400°F (204°C), making it ideal for powder coating, anodization, and other high-temperature industrial processes. The tape's superior chemical resistance combined with its thermal stability ensures reliable performance in the most challenging work environments.
Designed as a thicker, more durable version of the 3M Polyester Tape 8901, this 3.4 mil thick tape delivers enhanced durability and extended wear life. The silicone adhesive provides exceptional clean removal from a variety of difficult surfaces including silicone-coated substrates, avoiding slivering and breaking during removal. With dimensions of 18 inches width by 72 yards length, each case contains 2 rolls, providing substantial coverage for industrial masking operations. The translucent blue backing enables easy identification and precise positioning during application.
This professional-grade tape excels in permanent splicing operations on silicone liners, papers, and films subject to high temperatures. It serves as an effective barrier for metal surface protection during chemical milling baths containing acids or caustic solutions, and functions as a flash breaker in metal bonding processes. The pressure-sensitive formulation ensures immediate adhesion without requiring heat or solvents, while the tear-resistant polyester backing maintains integrity throughout demanding masking operations.
