General Purpose Foil Tapes

These aluminum tapes reflect more than heat. They reflect our reputation for high quality sealing.

3MGeneral Purpose Aluminum Foil Tapes 1449 and 1450 allow you to give

sensitive surfaces and assemblies the extra sealing and holding protection they demand. The dead-soft aluminum foil backing affords excellent heat and light reflection to protect against high temperatures and U.V. degradation. The foil also serves as an excellent barrier against moisture, dust, flame, and certain chemicals.

In selecting your tape, consider which type of adhesive best meets your needs. Tape 1449 has an acrylic adhesive, while 1450 features synthetic rubber. Acrylic supplies superior temperature, U.V., and solvent resistance. It provides excellent age life and is ideal for harsh, long-term outdoor environments. Rubber offers high initial tack and performs best indoors, in short-term, stable environments.
