Premium high-temperature masking tape with silicone adhesive for demanding industrial applications. Operates -60°F to 400°F with clean removal and excellent chemical resistance. 4 in x 72 yd rolls, 8 per case.
3M Polyester Tape 8901 is a premium high-temperature masking tape engineered for demanding industrial applications where thermal resistance and clean removal are critical. This thin, conformable polyester tape features a silicone adhesive that bonds exceptionally well to difficult surfaces, including silicone-coated materials. The translucent blue backing provides excellent visibility for precise positioning and identification during masking operations. With a working temperature range from -60°F (-50°C) to 400°F (204°C), this tape excels in powder coating, composite bonding, and chemical processing applications.
The tape delivers outstanding performance in high-temperature masking operations such as powder coat painting, where it removes cleanly and in one piece from most surfaces without slivering or breaking. Its superior chemical resistance makes it ideal for use in anodizing processes and acid or caustic chemical milling baths. The pressure-sensitive silicone adhesive ensures reliable adhesion under extreme temperature fluctuations and demanding work conditions. With 115% elongation at break, the tape maintains flexibility while conforming to complex part geometries.
Each case contains 8 rolls of tape, with each roll measuring 4 inches wide by 72 yards long and featuring a 0.9 mil thickness. The tape meets rigorous industry standards including ASTM D3330, ASTM D3652, and ASTM D3759, ensuring consistent quality and performance. Ideal for industrial and occupational use, this tape is the preferred choice for manufacturing facilities, composite bonding operations, and specialized coating processes requiring reliable high-temperature masking solutions.
