3M 7000123400 Vhb Foam Tape 4929 Black 0.5in X 72yd 25 Mil

Product Description

The 3M 7000123400 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape sold under the VHB Tape 4929 product line. At 25 mil thick, it delivers a firm yet conformable bond to high surface energy substrates including many metals, glass, and rigid plastics. The tape ships on a roll measuring 0.5 inches wide by 72 yards long and includes a paper release liner for clean handling during application. Weighing approximately 1.18 pounds per roll, it is well-suited for bonding, cushioning, vibration damping, and impact resistance in demanding assembly environments. Installation is straightforward and does not require fasteners, rivets, or liquid adhesives.

VHB Tape 4929 is used across a wide range of industrial, commercial, and construction applications where permanent or semi-permanent bonding of panels, nameplates, trim, gaskets, or mounting components is required. It performs on high surface energy materials such as coated metals, architectural cladding, and rigid thermoplastics. Typical installers include sheet metal workers, glaziers, electrical panel assemblers, HVAC fabricators, and general contractors working with pre-finished or painted substrates where mechanical fasteners are undesirable.

Key Features

• 25 mil total thickness for gap-filling conformability and cushioning
• Closed-cell acrylic foam core provides vibration damping and impact resistance
• Double-sided construction bonds two surfaces in a single tape layer
• Bonds high surface energy substrates without mechanical fasteners
• Paper liner included for clean, controlled application
• Black color for discrete appearance in visible assemblies

Compatibility

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

Installation Notes

Surface preparation is critical for maximum bond strength — clean substrate surfaces thoroughly to remove oils, dust, and contaminants before application. Apply firm, even pressure across the tape after positioning to activate the pressure-sensitive adhesive. Allow adequate dwell time at room temperature before subjecting the bond to load or stress. This tape is intended for permanent or semi-permanent bonding; removal may damage the substrate or the bonded assembly.
