Highlights
- Linered version of 3M™ Aluminum Foil Tape 425
- Thermally conductive tape helps dissipate heat and improves heating and cooling efficiency to protect temperature-sensitive materials
- Resistant to chemicals to protect surfaces during de-paint process and other chemical masking operations
- Highly engineered acrylic adhesive provides long term durability, but removes cleanly after harsh masking applications
- Withstands exposure to flame, weathering, moisture, and UV Rays
- Heat resistant and light reflective tape protects surfaces and enhances lighting efficiency
- Dead soft aluminum foil backing conforms to curved and uneven surfaces
3M™ Aluminum Foil Tape 427 is the go-to foil tape for numerous applications across a broad range of industries. Comprised of a dead-soft aluminum foil backing with a highly engineered pressure-sensitive acrylic adhesive, it is ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing, and de-paint operations.
Consisting of a dead soft, thermally conductive aluminum backing, 3M™ Aluminum Foil Tape 427 dissipates heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. This version of 3M™ Aluminum Foil Tape 427 has a liner, making it suitable for die cutting applications. Coated with highly engineered acrylic adhesive, it is capable of withstanding exposure to high heat and humidity while maintaining a strong and reliable bond. This tape can withstand a variety of moisture, weathering, UV, and solvents in order to provide an excellent work life, indoors or out.
Suggested 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
