3M™ Aluminum Foil Tape 427 is a versatile and high-performance tape designed for a multitude of applications across various industries. This tape features a dead soft aluminum foil backing paired with a highly engineered pressure-sensitive acrylic adhesive, making it ideal for tasks such as heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing, and de-paint operations.
- Heat and Humidity Resistance: The thermally conductive aluminum backing dissipates heat over the surface of the tape, reducing hot spots and protecting substrates from high temperatures. The tape maintains a strong bond even in high heat and humid conditions.
- Durable Adhesive: Coated with a highly engineered acrylic adhesive, the tape offers excellent durability and can withstand exposure to moisture, weathering, UV, and solvents, ensuring long-lasting performance indoors and outdoors.
- Easy Die-Cutting: The linered version of 3M™ Aluminum Foil Tape 425, making it suitable for die-cutting applications for precise and easy application.
- Wide Temperature Range: Capable of operating within a temperature range of -65° to 300°F (-54° to 149°C), making it suitable for various demanding environments.
- Compliance and Safety: UL Recognized to UL 746C and Classified by UL to UL 723 "L" for low flammability rating. It can also be certified to meet L-T-80C and complies with F.A.R 25.853(a).
Recommended Applications:
- Heat shielding of delicate parts
- Heat reflecting
- Masking in chemical paint stripping applications
- Moisture barrier
- Light reflecting for light enhancement
- Chemical milling
- Seaming and sealing
- Refrigerator and freezer coil attachment
