Premium high-temperature polyester masking tape with silicone adhesive, rated -60°F to 400°F, offering clean removal and excellent chemical resistance for industrial applications including powder coating and composite bonding.
3M™ Polyester Tape 8902 is a premium high-temperature masking tape designed for demanding industrial applications where extreme temperatures and chemical resistance are critical. This advanced polyester tape features a silicone adhesive formulation that delivers clean removal during high-temperature masking operations such as powder coating, making it ideal for precision paint line applications. The tape maintains exceptional performance across a wide temperature range from -60°F (-50°C) to 400°F (204°C), ensuring reliable adhesion and removal in the most challenging environments.
The tape is engineered as a thicker, more durable version of the 3M Polyester Tape 8901, providing superior durability and extended wear life for demanding industrial processes. Its translucent blue backing offers excellent tear resistance and easy identification for precise positioning during application. The silicone adhesive ensures clean, one-piece removal from most surfaces without slivering or breaking, making it perfect for masking metal surfaces in acid or caustic chemical milling baths, composite bonding operations, and permanent splicing applications.
With excellent thermal and chemical resistance while maintaining flexibility, this tape excels in multiple industrial applications including masking parts for powder coat painting, splicing of silicone liners and films, flash breaker applications in metal bonding processes, and protective applications during shipping and handling. The pressure-sensitive silicone adhesive performs reliably under broad temperature ranges, making it suitable for anodization processes and other demanding work conditions. Commonly used in appliance, automotive, construction, electronics, and specialty vehicle manufacturing industries.
