Premium blue polyester masking tape with silicone adhesive for high-temperature applications from -60°F to 400°F, ideal for powder coating and chemical-resistant masking operations.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications requiring thermal and chemical resistance. This blue polyester tape features a silicone adhesive that provides clean removal from a variety of surfaces, making it ideal for powder coating operations and high-temperature masking applications. The tape operates reliably across an extreme temperature range from -60°F (-50°C) to 400°F (204°C), ensuring consistent performance in the most challenging work environments.
This tape is a thicker, more durable version of the 3M Polyester Tape 8901, offering superior durability and extended wear characteristics. The translucent blue backing is tear-resistant and provides easy identification and positioning during application. With excellent chemical resistance, the tape performs effectively in chemical processes such as anodization, acid milling, and caustic chemical baths. The pressure-sensitive silicone adhesive bonds securely to difficult surfaces including silicone-coated materials while maintaining the ability to remove cleanly in one piece without slivering or breaking.
Commonly used in aerospace, automotive, electronics, and general industrial applications, this tape excels in permanent splicing operations on silicone liners, films, and papers subject to high temperatures. It also serves as an effective protective tape during shipping and handling operations, reducing scratches and damage to finished products. The tape meets ASTM D3330, ASTM D3652, and ASTM D3759 specifications, ensuring compliance with industry standards for masking and surface protection applications.
