Premium 3M Polyester Tape 8902 designed for high-temperature masking operations with silicone adhesive, chemical resistance, and clean removal. Ideal for powder coating, anodization, and demanding industrial applications from -60°F to 400°F.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications requiring thermal and chemical resistance. This thicker, more durable polyester tape features a silicone adhesive that bonds excellently to difficult surfaces including silicone-coated substrates. The tape maintains superior performance across an exceptional temperature range from -60°F (-50°C) to 400°F (204°C), making it ideal for powder coating, anodization, and other high-temperature processes. The translucent blue polyester backing provides excellent tear resistance, easy identification, and positioning during application. With 140% elongation at break and 46 lb/in tensile strength, this tape delivers reliable performance in demanding work conditions.
The 3M Polyester Tape 8902 excels in high-temperature masking operations such as powder coat painting, where it provides sharp paint lines and clean removal without slivering or breaking. The silicone adhesive formulation ensures the tape removes cleanly and in one piece from most surfaces, avoiding residue and damage to underlying materials. Its superior chemical resistance makes it effective in chemical processes including acid or caustic chemical milling baths. The tape is also commonly used for splicing operations on silicone liners, papers, and films subject to high temperatures, as well as for protective purposes during shipping and handling operations.
This industrial-grade tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, confirming its quality and reliability. Each case contains 24 rolls of 2-inch wide tape with 72-yard length per roll, providing ample supply for production environments. The 3.4 mil thickness represents a significant upgrade over the thinner 3M Polyester Tape 8901, offering enhanced durability and extended wear life for the most demanding applications.
