Premium high-temperature polyester masking tape with silicone adhesive, operating from -60°F to 400°F, ideal for powder coating and composite bonding applications.
3M Polyester Tape 8901 is a premium high-temperature masking tape engineered for demanding industrial applications. This thin, conformable polyester tape features a silicone adhesive that bonds exceptionally well to difficult surfaces, including silicone-coated surfaces. With a translucent blue backing that provides easy identification and positioning, this tape is specifically designed for powder coating, composite bonding, and chemical processing applications. The tape operates reliably across an extreme temperature range from -60°F (-50°C) to 400°F (204°C), making it ideal for environments requiring superior thermal and chemical resistance.
The 3M Polyester Tape 8901 excels in high-temperature masking operations such as powder coat painting, delivering sharp paint lines and clean removal without slivering or breaking. Its pressure-sensitive silicone adhesive provides excellent performance on a variety of substrates while maintaining flexibility. The tape removes cleanly in one piece from most surfaces, reducing waste and improving efficiency. With good chemical resistance, this tape performs effectively in chemical processes including anodizing and acid or caustic chemical milling baths.
Each case contains 24 rolls of 2-inch width by 72-yard length tape with 0.9 mil thickness, offering bubble-free application. The tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, ensuring consistent quality and performance. Recommended applications include masking parts for high-temperature powder coat painting, splicing of silicone liners and films, holding parts during composite bonding operations, and protective tape to reduce scratches during handling and shipping. This product is intended for industrial and occupational use only.
