3M 7000048734 Vhb Tape Gray 45 Mil 0.75 in X 36 Yd

Product Description

The 3M 7000048734 is a gray, double-sided, closed-cell acrylic foam tape in the VHB 4941F series, designed for permanent structural bonding without mechanical fasteners. At 45 mil thick, it delivers a conformable bond layer that accommodates surface irregularities while providing cushioning, vibration damping, and impact resistance. The pressure-sensitive adhesive bonds to high and medium surface energy substrates and resists plasticizer migration, making it suitable for long-term assemblies exposed to plasticized materials. It ships on a polyethylene film liner and is available in a 0.75-inch by 36-yard roll. Licensed professionals and industrial assembly technicians use this tape in applications requiring a clean, load-bearing bond line.

This tape is well suited for bonding metal, glass, painted surfaces, and rigid plastics in both commercial construction and manufacturing assembly environments. Typical applications include panel attachment, sign fabrication, glazing, and equipment enclosure assembly. The closed-cell foam core also provides a degree of environmental sealing along the bond line. Its UL 746C listing makes it appropriate for use in electrical and electronic component assemblies where flammability and material compatibility ratings are required by specification.

Key Features

• 45 mil closed-cell acrylic foam construction for conformable, permanent bonds
• Double-sided pressure-sensitive adhesive bonds high and medium surface energy substrates
• Plasticizer resistant for durability in assemblies containing PVC and similar materials
• Cushioning and vibration damping properties reduce mechanical stress at the bond line
• PE film liner for controlled application and handling convenience
• UL 746C listed for use in electrical and electronic component applications

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and rigid plastics; suitable for panel bonding, sign assembly, glazing, and electronic enclosure applications where a structural foam tape is specified.

Installation Notes

Surface preparation is critical for VHB tape performance — clean all bonding surfaces with an appropriate solvent cleaner and allow to dry fully before applying tape. Apply firm, even pressure across the entire bond area to ensure full adhesive contact; a roller is recommended for consistent results. Allow adequate dwell time at room temperature before applying service loads to the assembly. This product is intended for permanent bonding; removal will likely damage the substrate or the bonded assembly.
