3M 7000123345 Vhb Tape 4930 White 1 Inch X 72 Yd 25 Mil

Product Description

The 3M 7000123345 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape sold in a 1-inch-wide by 72-yard roll at 25 mil thick. The foam core is firm and carries a paper liner for controlled application. At 25 mil, the tape delivers meaningful cushioning, vibration damping, and impact resistance alongside its primary bonding function. It is designed to bond high-surface-energy substrates such as metals, glass, and many rigid plastics. Installers across construction, glazing, sign fabrication, and general industrial assembly use this tape where mechanical fasteners are impractical or where a cleaner finished appearance is required. The tape carries a UL 746C listing.

This roll format suits continuous runs on assembly lines, panel bonding on architectural surfaces, and trim or gasket attachment in light commercial construction. The paper liner releases cleanly, making hand application straightforward for a single technician. The acrylic foam construction maintains bond integrity across a range of temperatures and resists long-term creep better than rubber-based foam alternatives. Typical applications include bonding metal panels, attaching signage to frames, and securing weatherstripping or trim components where both adhesion and damping are needed in the same joint.

Key Features

• 25 mil closed-cell acrylic foam core provides cushioning and vibration damping in a single layer
• Double-sided pressure-sensitive adhesive bonds without primers on most high-surface-energy substrates
• Paper liner for clean, controlled application during hand or machine dispensing
• UL 746C listed for use in evaluated plastic component assemblies
• 1-inch width by 72-yard length minimizes splices on long continuous runs
• White foam color suits applications where tape edges may be visible in the finished assembly

Compatibility

Designed for bonding high-surface-energy substrates including metals, glass, and rigid plastics in construction, sign, and industrial assembly applications.

Installation Notes

Surface preparation is critical for pressure-sensitive tape adhesion — clean and dry the substrate thoroughly before application, removing oils, dust, and loose coatings. Apply firm, uniform pressure across the full bond area immediately after positioning; a roller tool improves contact and bond development. Allow adequate dwell time before loading the joint, as acrylic adhesive systems reach full strength over hours rather than seconds. No special tools or licensed trade are required, but follow applicable building or assembly specifications for structural or load-bearing joints.
