3M™ Tape, 60 yd L, 1 in W, 4.6 mil THK, Silver, 1.8 mil, Acrylic, Aluminum Foil, 6%, 28 in-lb

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. Consisting of a dead soft, thermally conductive aluminum backing, aluminum foil tape 425 dissipates heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. Coated with highly engineered acrylic adhesive, it is capable of withstanding exposure to high heat (up to 300 degrees F) 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.
Features
• 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
