3M 7000123928 Vhb Foam Tape 0.5in X 72yd 25 Mil Black

Product Description

The 3M 7000123928 is a double-sided, closed-cell acrylic foam tape with a polyethylene film liner, designed for high-strength bonding without mechanical fasteners. At 25 mil thick and 0.5 inches wide on a 72-yard roll, this tape delivers reliable adhesion to high, medium, and medium-low surface energy substrates. The conformable foam core provides cushioning, vibration damping, and impact resistance alongside its bonding function. It carries a UL 746C listing, making it suitable for applications where listing compliance is required. Trade professionals and industrial assembly personnel use this tape where clean, load-bearing bonds are specified in lieu of rivets, screws, or welds.

This tape is suited for residential and commercial applications involving mounting, attaching, or sealing dissimilar materials including painted metals, plastics, and composite surfaces. Typical use cases include panel bonding, sign mounting, trim attachment, and sealing applications where conformability over irregular surfaces is needed. The black color and closed-cell construction make it a common choice where a finished appearance is required and where the bond must resist moisture intrusion at the joint.

Key Features

• 25 mil thick closed-cell acrylic foam core for conformability over irregular surfaces
• Double-sided pressure-sensitive construction bonds without mechanical fasteners
• Bonds high, medium, and medium-low surface energy substrates
• Provides cushioning, vibration damping, and impact resistance at the bond line
• UL 746C listed for applications requiring recognized component status
• Polyethylene film liner for clean handling and controlled unwind

Compatibility

Designed for bonding applications involving high, medium, and medium-low surface energy substrates including metals, plastics, and composites where a conformable, load-bearing double-sided tape is specified.

Installation Notes

Surface preparation is critical — clean bonding surfaces of oils, dust, and loose material before application to achieve rated adhesion. Apply firm, even pressure across the full bond area after positioning; bond strength increases over the first 24 to 72 hours as the acrylic adhesive sets. Follow the substrate and application temperature guidelines specified by the manufacturer and applicable project specifications. This tape is not a substitute for structural fasteners in life-safety or primary load-bearing assemblies.
