High-temperature polyester masking tape with silicone adhesive, rated for -60°F to 400°F, ideal for powder coating and chemical processes. 4 in x 72 yd rolls with clean removal properties.
3M Polyester Tape 8901 is a premium high-temperature masking tape engineered for demanding industrial applications. This thin, conformable polyester tape features a pressure-sensitive silicone adhesive that bonds exceptionally well to difficult surfaces, including silicone-coated materials. With a translucent blue backing that provides easy identification and positioning, this tape excels in powder coat painting operations, delivering sharp paint lines while removing cleanly and in one piece to avoid slivering and breaking.
Designed to perform under extreme temperature conditions ranging from -60°F (-50°C) to 400°F (204°C), the tape maintains its integrity and adhesive properties across demanding industrial environments. The polyester film backing offers excellent thermal and chemical resistance while maintaining flexibility for conforming to various surface contours. The silicone adhesive formulation provides superior performance in chemical processes such as anodizing and metal surface protection, making it ideal for both temporary masking and permanent splicing operations.
This professional-grade tape is specifically formulated for industrial and occupational use, meeting ASTM D3330, ASTM D3652, and ASTM D3759 specifications. Each case contains 8 rolls, with each roll measuring 4 inches wide by 72 yards long and 0.9 mil thick, providing ample material for high-volume production environments. The tape's tear-resistant backing and superior adhesive properties make it the preferred choice for aerospace, automotive, electronics, and specialty vehicle manufacturing applications.
