The 3M 1521CW Venture Tape is a conformable 2.8 mil aluminum foil tape designed for masking, sealing, heat shielding, and light-reflecting applications. It uses a cold-weather acrylic adhesive that bonds at temperatures as low as -10°F (-23°C) and provides a service temperature range from -40°F (-40°C) to 250°F (121°C). The dead soft aluminum backing conforms to irregular surfaces and fibrous or sheet metal ductwork, and the tape meets UL723 and CAN/ULC S102 flame/smoke ratings.
Cold-weather acrylic adhesive bonds at -10°F (-23°C); service temperature -40°F (-40°C) to 250°F (121°C)
Dead soft aluminum foil backing; conformable, hand-tearable, resists lifting and curling
Meets UL723 and CAN/ULC S102 flame and smoke ratings; high puncture and tear resistance
