3M Venture Tape FSK Facing Tape 1525CW is a premium cold-weather adhesive tape with foil/scrim/kraft backing, designed for sealing HVAC ducts and insulation. Features acrylic adhesive, operates from -40°F to 240°F, meets UL723 and ASTM standards, and includes 8 rolls per case.
3M™ Venture Tape™ FSK Facing Tape 1525CW is a premium adhesive tape designed for sealing and patching FSK-faced duct wrap insulation and serving as a vapor seal for reinforced aluminum faced fiberglass, mineral wool thermal insulation, and sheet metal applications. This industrial-grade tape features a foil/scrim/kraft (FSK) lamination coated with a solvent acrylic, pressure-sensitive adhesive that bonds and seals at temperatures as low as -10°F (-23°C), making it ideal for demanding cold weather conditions. The tape is constructed with a 5.5 mil tri-directional reinforced backing that provides superior resistance to weathering, mold, UV, and environmental conditions while maintaining excellent performance in both cold and hot temperature applications.
The tape's flexible backing conforms exceptionally well to irregular surfaces, curves, and shaped ductwork, ensuring a durable and reliable seal without requiring special tools or application methods. With a service temperature range from -40°F/-40°C to 240°F/116°C, this versatile tape performs consistently across a wide spectrum of environmental conditions. Once bonded, it provides excellent holding power for extended periods with superior aging properties that resist lifting and curling. The 1525CW model meets the rigorous UL723 flame/smoke rating (10/10) and complies with ASTM C1136 Type II and IV specifications, ensuring safe use in demanding industrial applications.
Each case contains 8 rolls of tape, with each roll measuring 123.75 mm (4.87 inches) in width and 45.7 meters (50 yards) in length. The acrylic adhesive is specifically engineered for cold weather applications while delivering quick stick at normal temperatures and maintaining superior low-temperature performance. For optimal results, store the tape in a cool, dry environment. This product is intended for industrial and occupational use only and must be selected and used in compliance with applicable health and safety regulations and standards.
