Superb Temperature Resistance

When sealing ducts and other surfaces for heating, ventilation and air conditioning systems, it’s essential to have a strong, long-lasting foil tape that can stand up well to hot and cold temperatures. The 3M™ Foil Tape 3340 has the combination of a foil backing and acrylic adhesive that gives our tape a superb operational temperature range of -40°F (-40°C) to 300°F (149°C). The benefits don’t end there; the foil backing also serves as an excellent barrier against moisture, dust and many chemicals — making it strong, durable and long-lasting. The very low moisture vapor transmission rate makes the tape a good sealant and the acrylic adhesive supplies superior temperature and UV resistance to give you a strong, lasting and reliable bond. 3M™ Foil Tape 3340 is used in a variety of applications across a number of industries, including: transportation, specialty vehicle, metalworking, construction, automotive, military and government, general industrial, MRO, electronics and aerospace.
