Premium high-temperature polyester masking tape with silicone adhesive for powder coating, composite bonding, and chemical processing. Works from -60°F to 400°F with clean removal and excellent thermal/chemical resistance.
3M Polyester Tape 8901 is a premium high-temperature masking tape engineered for demanding industrial applications including powder coating, composite bonding, and chemical processing. This thin and conformable polyester tape features a silicone adhesive that provides exceptional clean removal from a variety of difficult surfaces, including silicone-coated materials. The translucent blue backing is tear-resistant and offers excellent visibility for precise positioning and identification during masking operations.
The tape delivers outstanding performance across an extensive temperature range from -60°F (-50°C) to 400°F (204°C), making it ideal for high-temperature masking operations such as powder coat painting. With excellent thermal and chemical resistance while maintaining flexibility, this tape excels in demanding work conditions including anodizing, acid baths, and caustic chemical milling. The pressure-sensitive silicone adhesive ensures clean removal in one piece from most surfaces, avoiding slivering and breaking that can compromise paint lines and surface quality.
Recommended for masking parts during high-temperature powder coating, splicing of silicone liners and films, holding parts during composite bonding operations, masking metal surfaces in chemical baths, and protective applications to reduce scratches during handling and shipping. Each roll measures 16 inches wide by 72 yards long with a 0.9 mil thickness, providing ample coverage for industrial masking projects. This product meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications and is intended for industrial and occupational use only.
