3M Aluminum Foil Tape 427 Silver, 2 in x 60 yd 4.6 mil, 24 rolls per case Bulk

Our 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. It is a linered version of our 3M aluminum foil tape 425, making it suitable for die cutting applications. Coated with our 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. 3M aluminum foil tape 427 is UL recognized to UL 746C (file e 122798) and classified by UL to UL 723 "L" for low flammability rating (file R 7311). It can be certified to meet SAE-AMS-T-23397 and L-T-80C and meets F.A.R 25.853(a).

• 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
• Heat and light reflective tape protects surfaces and enhances lighting efficiency
• Dead soft aluminum foil backing conforms to curved and uneven surfaces
