Premium high-temperature polyester masking tape with silicone adhesive for demanding industrial applications, operating reliably from -60°F to 400°F with excellent chemical resistance and clean removal.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape engineered for demanding industrial applications where extreme thermal conditions are present. This thicker, more durable polyester tape features a silicone adhesive that provides excellent bonding to difficult surfaces including silicone-coated materials. The tape excels in high-temperature powder coat painting operations, delivering sharp paint lines with clean, one-piece removal that avoids slivering and breaking. With a translucent blue backing that is tear-resistant and easy to identify, this tape works reliably across a broad temperature range from -60°F (-50°C) to 400°F (204°C).
This tape offers exceptional chemical resistance and performs flawlessly in demanding work conditions such as anodization, acid milling, and caustic chemical processes. The polyester film backing maintains excellent flexibility while providing superior thermal and chemical resistance. As a thicker version of the 3M Polyester Tape 8901, the 8902 provides enhanced durability and extended wear life for critical masking applications. The pressure-sensitive silicone adhesive ensures reliable performance across a wide range of industrial environments and substrates.
3M Polyester Tape 8902 is commonly used for masking parts during high-temperature powder coat painting, splicing of silicone liners and films, holding parts during composite bonding operations, flash breaker applications in metal bonding processes, protective tape during shipping and handling, and as a barrier for separation of dissimilar metals. Each case contains 36 rolls of 1-inch wide tape, with each roll measuring 72 yards in length, providing ample supply for production environments.
