Professional-grade FSK facing tape with cold weather acrylic adhesive for HVAC duct sealing. Bonds at -10°F, operates -40°F to 240°F. UL723 rated, 24 rolls per case.
3M™ Venture Tape™ FSK Facing Tape 1525CW is a professional-grade adhesive tape specifically engineered for sealing and patching FSK-faced duct wrap insulation in demanding cold weather conditions. This 5.5 mil tri-directional reinforced tape features a foil/scrim/kraft laminated backing coated with a cold weather acrylic adhesive that bonds and seals at temperatures as low as -10°F (-23°C). The tape is ideal for vapor sealing reinforced aluminum faced fiberglass, mineral wool thermal insulation, and sheet metal applications. With a service temperature range from -40°F/-40°C to 240°F/116°C, this versatile tape performs exceptionally well in both extreme cold and demanding heat and humidity conditions.
The FSK Facing Tape 1525CW combines superior puncture and tear resistance with excellent flexibility, allowing it to conform seamlessly to curved or irregular surfaces without requiring special tools or application methods. Its flexible backing ensures easy installation on both fibrous and sheet metal ductwork, making it an ideal choice for HVAC sealing applications and exterior/interior seam work. The tape meets UL723 flame/smoke rating (10/10) and ASTM C1136 Type II and IV specifications, ensuring safe use in commercial and industrial applications. Once bonded, the tape provides excellent holding power for extended periods with superior aging properties that resist lifting and curling.
Designed for industrial and occupational use, this premium tape represents decades of 3M's adhesive innovation and engineering excellence. The case quantity of 24 rolls per case provides excellent value for contractors, installers, and facilities managers requiring reliable duct sealing solutions. For optimal performance, store the tape in a cool, dry environment before use.
