High-temperature polyester masking tape with silicone adhesive for clean removal in powder coating, composite bonding, and chemical processing. Operates from -60°F to 400°F with excellent thermal and chemical resistance.
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 substrates, making it ideal for powder coating operations, composite bonding, and chemical processing applications. The translucent blue backing provides excellent tear resistance and enables easy identification and precise positioning during application.
With an impressive operating temperature range from -60°F (-50°C) to 400°F (204°C), this tape delivers consistent performance in the most challenging work environments. The silicone adhesive ensures clean, one-piece removal without slivering or breaking, protecting paint lines and surface integrity. The tape demonstrates exceptional chemical resistance, making it suitable for use in acid and caustic chemical milling baths, anodizing operations, and other aggressive chemical processes. Its 0.9 mil thickness and 115% elongation at break provide the flexibility needed for conforming to complex geometries while maintaining structural integrity.
Ideal for masking metal surfaces, splicing silicone liners and films, and holding parts during composite bonding, 3M Polyester Tape 8901 is backed by decades of 3M innovation in adhesive technology. The 48-inch width and 72-yard length per roll provide ample coverage for industrial production environments. This tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, ensuring compliance with industry standards for high-temperature masking applications.
