Introducing the 3M™ Polyester Tape 8402, a premium solution engineered for high temperature masking applications, splicing, and protection. This highly versatile tape is crafted with a silicone adhesive that ensures it adheres flawlessly to silicone-coated surfaces, providing a clean, one-piece removal from most substrates. Its thin, conformable design makes it the ideal choice for a wide range of industrial tasks where high temperature and chemical resistance are paramount.
- High Temperature Resilience: Designed to withstand extreme temperatures, this tape operates efficiently in environments ranging from -60°F (-50°C) to 425°F (218°C), making it perfect for applications requiring high heat tolerance.
- Exceptional Chemical Resistance: Its durability is unmatched in challenging conditions, including exposure to acids and caustic chemicals during milling baths, ensuring performance in the most demanding work conditions.
- Effortless Clean Removal: The silicone adhesive guarantees that the tape can be removed cleanly and in one piece from most surfaces, reducing work time and enhancing productivity.
- Vivid Green Color for Easy Identification: The tape's distinctive green hue simplifies identification, streamlining processes and minimizing errors.
- Flexible and Conformable: Its conformable nature ensures a tight seal over irregular shapes and surfaces, offering reliable protection and splicing capabilities.
- Versatile Application Range: Whether it's splicing silicone liners, masking metal surfaces in chemical baths, holding parts during composite bonding, or serving as a flash breaker in metal bonding processes, this tape delivers exceptional performance.
Usage and Maintenance: For optimal application, ensure surfaces are clean, dry, and free of dust or oil before tape application. When used as a protective tape, it can significantly reduce scratches during handling and shipping, preserving the integrity of the product. In high temperature bake cycles, it serves as an effective paint mask, withstanding the rigors of the process without compromising its adhesive quality or leaving residues. After use, the tape can be removed cleanly, maintaining the surface's integrity and appearance. Always store in a cool, dry place away from direct sunlight to preserve its properties.
