Withstands Exposure to High Heat and Humidity 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. 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 Splicing of thin gauge foils Plastic protection 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). Temperature use range is from -65° to 300°F (-54° to 149°C).
