3M 7000123934 Vhb Foam Tape 45 Mil 0.5 in X 36 Yd Black

Product Description

The 3M 7000123934 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape designed for high-strength bonding in demanding industrial and construction applications. At 45 mil thick, the tape conforms to irregular surfaces and bonds securely to high and medium surface energy substrates. It ships in roll form and is sold in a small pack configuration measuring 0.5 inches wide by 36 yards long. The black PE film liner aids in handling and removal during installation. Suitable for use by contractors, fabricators, and trade professionals who need a reliable structural adhesive alternative to mechanical fasteners.

This tape is used across a broad range of applications including panel bonding, sign assembly, metal fabrication, glazing, and general industrial mounting. It performs well in environments where cushioning, vibration damping, and impact resistance are required. The closed-cell acrylic foam core resists plasticizer migration, making it appropriate for use with vinyl and similar materials. Its conformability allows it to maintain contact with curved or uneven surfaces, which is especially useful in HVAC panel assembly, electrical enclosure mounting, and architectural cladding applications.

Key Features

• 45 mil closed-cell acrylic foam construction provides cushioning and impact resistance
• Double-sided pressure-sensitive adhesive bonds to high and medium surface energy substrates
• Plasticizer resistant for compatibility with vinyl and PVC surfaces
• Conformable design maintains contact on curved and irregular surfaces
• PE film liner for handling convenience and clean application
• UL listing 746C for use with polymeric materials

Compatibility

Designed for bonding to high and medium surface energy substrates including metals, glass, and rigid plastics. Not recommended for low surface energy substrates such as untreated polyethylene or polypropylene without surface preparation.

Installation Notes

Surface preparation is critical for maximum adhesion — clean all bonding surfaces free of oil, dust, and loose particles before application. Apply firm pressure across the full tape surface to activate the pressure-sensitive adhesive. Allow adequate dwell time at room temperature before applying full load. Follow applicable building or equipment manufacturer guidelines when using structural adhesive tape as a mechanical fastener replacement.
