3M 7000123933 Vhb Foam Tape 25 Mil 1 Inch X 72 Yd Black

Product Description

The 3M 7000123933 is a black, double-sided, pressure-sensitive closed-cell acrylic foam tape in the VHB 4919F series. At 25 mil thick, it conforms to irregular surfaces and bonds high and medium surface energy substrates without mechanical fasteners. The PE film liner keeps the adhesive protected until installation. It provides cushioning, vibration damping, and impact resistance, and is resistant to plasticizer migration — an important characteristic when bonding to PVC or other plasticizer-containing materials. The UL 746C listing confirms suitability for use with components and materials in evaluated applications. Each roll measures 1 inch wide by 72 yards long. Installers in sign, glazing, panel assembly, and general industrial trades use this tape for permanent structural bonding where a clean, fastener-free finish is required.

This tape is suited for residential and commercial applications where a conformable, high-strength bond is needed on smooth or lightly textured substrates. Typical use cases include bonding metal trim, plastic panels, nameplates, and architectural cladding. It performs well in applications where vibration or thermal cycling would loosen mechanical fasteners over time. The closed-cell foam core also provides a degree of environmental sealing along the bond line.

Key Features

• 25 mil total thickness for conformability on uneven or curved surfaces
• Double-sided pressure-sensitive adhesive eliminates need for mechanical fasteners
• Closed-cell acrylic foam core provides cushioning, damping, and impact resistance
• Plasticizer resistant — suitable for bonding PVC and other plasticizer-containing substrates
• UL 746C listed for use in applicable component and material evaluations
• PE film liner for clean handling and precise application

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and many rigid plastics. No specific equipment or system model compatibility was provided for this product.

Installation Notes

Surface preparation is critical for VHB tape bonds — substrates should be clean, dry, and free of oils, dust, and loose particles before application. Apply firm, even pressure across the full bond area immediately after positioning; a roller is recommended to achieve consistent contact. Do not expose the bond to full service loads until sufficient dwell time has elapsed at ambient temperature. Removal of cured VHB bonds typically requires mechanical means and may damage the substrate.
