High-strength aluminum foil tape with cold-weather acrylic adhesive for masking, sealing, and heat shielding. Performs in extreme temperatures from -40°F to 250°F. UL723 rated, hand tearable, and ideal for ductwork applications.
3M™ Venture Tape™ Aluminum Foil Tape 1521CW is a premium conformable 2.8 mil tape specifically engineered for masking, sealing, and heat shielding applications in demanding cold weather environments. This high-strength, dead soft aluminum foil tape features a cold-weather acrylic adhesive that applies easily at temperatures as low as -10°F (-23°C), making it ideal for fibrous and sheet metal ductwork applications. The tape bonds and seals reliably across a wide service temperature range from -40°F/-40°C to 250°F/121°C, providing superior performance in extreme environmental conditions.
The 1.4 mil aluminum backing delivers exceptional puncture and tear resistance while maintaining flexibility to conform easily to curved and irregular surfaces. This pressure-sensitive tape is hand tearable and installs quickly without requiring special tools or application methods, making it perfect for on-site installation. The tape meets UL723 flame/smoke rating (10/10 5/10) and CAN/ULC S102 classification, ensuring compliance with fire safety standards. It maintains its form without lifting or curling over extended periods, providing reliable long-term performance.
Each case contains 16 rolls (6 bags per case) of 72mm x 45.7m tape, offering excellent value for large-scale projects. This versatile tape excels in vapor sealing for reinforced fiberglass and mineral wool thermal insulation, as well as seam and joint sealing on sheet metal and fibrous ductwork. With superior resistance to weathering, mold, UV rays, and many chemicals, this 3M industrial tape is backed by exclusive 3M technical expertise and is suitable for construction, aerospace, automotive, appliance, and maintenance applications.
