Premium silicone-adhesive polyester tape for high-temperature masking operations up to 400°F with clean removal and excellent chemical resistance
3M™ Polyester Tape 8901 is a premium high-temperature masking tape engineered for demanding industrial applications including powder coat painting, chemical processing, and composite bonding operations. This thin, conformable polyester tape features a silicone adhesive that provides clean removal and excellent adhesion to difficult surfaces including silicone-coated materials. The translucent blue backing offers easy identification and positioning while maintaining tear resistance for professional results.
This versatile tape delivers exceptional performance across extreme temperature ranges from -60°F (-50°C) to 400°F (204°C), making it ideal for high-temperature masking operations where standard tapes fail. The silicone adhesive ensures clean, one-piece removal from most surfaces without slivering or breaking, providing sharp paint lines and professional finishes. With outstanding chemical resistance, the tape performs reliably in acid and caustic chemical milling baths, anodizing processes, and other demanding work environments.
Designed for industrial and occupational use, 3M Polyester Tape 8901 meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications. Each roll measures 18 inches wide by 72 yards long with a 0.9 mil thickness, providing ample coverage for multiple applications. The tape's flexibility combined with its robust polyester backing creates a reliable solution for protecting surfaces during handling, shipping, and complex manufacturing processes.
