Excels in Demanding Temperatures
3M™ Aluminum Foil Tape 3380 is coated with a pressure sensitive cold weather solvent acrylic adhesive specifically designed for cold weather applications. This adhesive performs well in both demanding temperature and humidity applications. It adheres immediately on contact to a variety of materials, including fibrous and sheet metal ducts. With a service temperature ranging from -40°F/-40°C to 260°F/127°C, this tape can be applied in a variety of environmental conditions. Once bonded, it will provide good holding power for extended periods with good aging properties that resist lifting and curling.
3M™ Metal Foil Tapes
Aluminum is just one of the metal-backed tapes available from 3M. Our foil tapes resist failure from common sources of degradation including moisture, ultraviolet rays and many chemicals, and are commonly used for reflecting, wrapping, masking, sealing, and more in applications from air ducts to washing machines. As with all 3M products, our 3M™ Aluminum Foil Tape 3380 is supported by exclusive 3M technical expertise and application advice. 3M aluminum foil tapes are suitable for demanding applications in construction, aerospace, automotive, appliance, maintenance, repair and operations and many more segments. They are also thermally conductive for heating/cooling efficiency.
