Premium high-temperature polyester masking tape with silicone adhesive for powder coating and industrial applications. Works from -60°F to 400°F with clean removal and excellent thermal/chemical resistance.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications. This blue polyester tape features a silicone adhesive that provides exceptional performance in extreme temperature conditions ranging from -60°F (-50°C) to 400°F (204°C). The tape is specifically designed for powder coating operations, chemical milling processes, and other high-heat applications where clean removal and precise paint lines are critical.
With a thickness of 3.4 mil and dimensions of 12 inches wide by 72 yards long per roll, this tape offers superior durability compared to its thinner counterpart, the 3M Polyester Tape 8901. The translucent blue backing provides excellent visibility for easy identification and precise positioning during application. The polyester film backing delivers outstanding thermal and chemical resistance while maintaining exceptional flexibility, making it ideal for use on silicone-coated surfaces and challenging substrates.
The silicone adhesive formulation ensures clean, single-piece removal from most surfaces without slivering or breaking, protecting finished surfaces from damage. This tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications and is commonly used for masking parts during powder coat painting, splicing operations on silicone liners and films, holding parts during composite bonding, flash breaking in metal bonding processes, and protective applications during shipping and handling. Each case contains 4 rolls, making it economical for high-volume industrial operations.
