3M 7000123401 Vhb Tape 4929 Black 0.75in X 72yd 25 Mil

Product Description

The 3M 7000123401 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape sold under the VHB Tape 4929 product line in black. At 25 mil thick, it delivers a firm, conformable bond layer suited for demanding assembly and mounting applications. The tape ships with a paper liner for handling convenience and is supplied in a roll measuring 0.75 inches wide by 72 yards long. Licensed contractors, industrial maintenance technicians, and fabricators use this tape to create structural bonds where mechanical fasteners are impractical or undesirable. Its closed-cell foam core also provides cushioning, vibration damping, and impact resistance as secondary functions.

VHB Tape 4929 is designed for bonding high surface energy substrates such as metals, glass, and many rigid plastics. Typical applications include panel attachment, sign assembly, equipment mounting, and gasketing in both residential and light commercial settings. The tape is applied by hand, making it practical for field installation without specialized equipment. It performs in applications where a clean, fastener-free appearance is required or where surface access is limited.

Key Features

• Double-sided pressure-sensitive adhesive bonds without mechanical fasteners
• 25 mil total thickness provides a firm yet conformable bond layer
• Closed-cell acrylic foam core delivers cushioning, vibration damping, and impact resistance
• Paper liner included for clean handling and precise positioning before final application
• Black finish suits visible or color-matched installations
• 0.75 inches wide by 72 yards per roll for high-volume or continuous-run use

Compatibility

Designed for bonding high surface energy substrates including metals, glass, and rigid plastics in industrial, commercial, and field assembly applications.

Installation Notes

Surface preparation is critical for full bond strength — clean substrate surfaces thoroughly to remove oil, dust, and loose material before application. Apply firm, even pressure across the tape width to achieve full contact adhesion. Avoid stretching the tape during application, as this can reduce long-term bond performance. Final bond strength develops over time after initial application.
