3M™ Venture Tape™ ASJ Facing Tape 1540CW is a premium industrial-grade duct sealing tape specifically engineered for cold weather and high humidity applications. This advanced tape features a white kraft, scrim and foil laminate backing combined with a proprietary cold weather acrylic adhesive, making it ideal for sealing all service jacket (ASJ) faced duct piping systems and as a vapor seal on ASJ-faced ductboard and pipe insulation. The tape measures 99mm in width with a total length of 45.7 meters per roll, packaged in convenient 12-roll cases for bulk applications.
Designed for demanding HVAC and duct work environments, this 10.8 mil tri-directional reinforced tape delivers exceptional performance across extreme temperature ranges from -40°F to 240°F (-40°C to 116°C). The flexible backing conforms seamlessly to curved and irregular surfaces, while the cold weather acrylic adhesive provides quick stick at normal temperatures and excellent low-temperature performance. Built-in mold inhibitor agents help prevent mold buildup in humid and damp conditions, ensuring long-term adhesive strength and effectiveness.
With its high puncture and tear resistance, this tape provides solid holding power for extended periods while resisting lifting and curling. The product is UL 723 Classified with a 15/0 Flame/Smoke Rating and meets ASTM1136 standards for Types I, II, III, and IV. Installation is straightforward and requires no special tools or application methods, making it suitable for professional contractors and industrial applications. Each case contains 12 rolls for maximum convenience and cost efficiency.
