Thermally conductive tape helps dissipate heat and improves heating and cooling efficiency to protect temperature sensitive materials Its chemical resistant nature ensures surfaces are protected 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 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 425 is the go-to foil tape for numerous applications across a broad range of industries. Comprised of a dead soft, aluminum foil backing and coated 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.
