3M 3520cw-silver_2x50 Venture Tape Aluminum Foil Tape Cold Weather Acrylic 2 Inches X 50 Yards Silver

Product Description

The 3M 3520cw-silver_2x50 Venture Tape Aluminum Foil Tape is a conformable, pressure-sensitive foil tape built for HVAC, construction, and general industrial applications. It is designed for sealing and masking tasks where durability and temperature resistance are essential. HVAC technicians, sheet metal workers, and commercial contractors rely on this tape for sealing ductwork seams and joints, both interior and exterior. The tape features a cold-weather acrylic adhesive that bonds quickly and holds firmly across a wide temperature range, from -40 degrees F to 250 degrees F. This makes it suitable for installations in harsh outdoor environments and cold storage facilities where standard adhesives may fail. The aluminum foil backing is 2 mil thick and is engineered to conform easily to irregular surfaces, fibrous insulation, and sheet metal ductwork. This flexibility allows technicians to wrap around corners and edges without the tape lifting, splitting, or curling over time. The total tape thickness without liner is 3.5 mil, providing a sturdy profile that still allows hand tearing without the need for a knife or dispenser. At 2 inches wide and 50 yards long, each roll covers a generous run of ductwork seams in a single application session. The silver foil finish also serves light-reflecting and general-purpose heat shielding purposes in mechanical and electrical enclosures. This tape meets the UL723 flame and smoke rating as well as the CAN/ULC S102 classification, meaning it satisfies fire and safety codes commonly required on commercial job sites. Tensile strength reaches 21 lb per inch, ensuring the tape resists tearing under mechanical stress. Whether used for HVAC duct sealing, insulation jacketing, or heat shielding, this tape delivers consistent and code-compliant performance.
