The 3M™ Polyimide Tape 8998 is a robust, high-performance tape crafted for high-temperature masking operations, featuring a dark amber polyimide backing combined with a high-quality silicone adhesive. This tape is engineered to withstand extreme conditions while providing superior sealing and clean removal capabilities.
- Heat Resistant Construction: The tape's 2.0 mil polyimide backing and 1.2 mil silicone pressure-sensitive adhesive are designed to perform under high temperatures, making it ideal for applications that require heat resistance up to 500°F/260°C.
- Seals and Removes Cleanly: It seals tightly upon contact and can be peeled off cleanly without leaving any residue, even after exposure to high temperatures, ensuring a smooth, clean surface post-application.
- Exceptional Durability: The tape offers excellent thermal, chemical, and abrasion resistance, making it suitable for challenging environments where other tapes might fail.
- Strong Tensile Strength: Its exceptional tensile strength allows it to break through cured paint, making it an excellent choice for tasks requiring a sharp, clean finish such as in the automotive and aerospace industries.
- Precision Application: The thin backing of the tape ensures sharp paint lines, which is essential for precise painting tasks in manufacturing and repair operations.
Usage and Maintenance: To ensure optimal performance, apply 3M™ Polyimide Tape 8998 to a surface that is clean and dry. This will maximize adhesion and effectiveness of the tape under high-temperature conditions. Regular checks should be conducted to ensure that the tape performs well, especially when used in environments with fluctuating temperatures or exposure to chemicals.
