3M™ Polyester Tape 8901 is a thin, conformable polyester tape ideal for masking in high temperature applications and adheres well to silicone coated surfaces. The translucent blue backing is tear resistant. Coated with a silicone adhesive, this tape functions well in masking for powder coating to provide sharp paint lines. It removes cleanly and in one-piece from most surfaces, avoiding slivering and breaking. This tape also excels in permanent splicing operations on silicone liners, papers and films subject to high temperatures. With good chemical resistance, this tape works effectively in chemical processes and demanding work conditions, such as anodizing. The pressure sensitive silicone adhesive performs under a broad range of temperatures.
Product Features
Operates at temperatures up to 400°F/204°C
Polyester films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility
Translucent blue backing provides easy identification and positioning
Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing, and adhesive transfer
Silicone adhesives adhere well to tough-to-stick-to surfaces like silicone liners and fixtures coated with mold release
Silicone adhesive removes cleanly from many surfaces
Construction
2.4 Mil Total Thickness
0.9 Mil Backing Thickness
Roll Length - 72 yards
Recommended Applications
Masking parts for high temperature powder coat painting
Splicing of silicone liners, films and papers
Holding parts or vacuum bags during composite bonding operations
Masking metal surfaces in acid or caustic chemical milling baths
Protective tape reduces scratches during handling and shipping
Specifications
Tensile Strength (lb/in) - 26
Elongation (%) - 115
Steel Adhesion (oz/in) - 29
