3M 7000048506 Vhb Tape 4951 White 0.75in X 36yd 45 Mil

Product Description

The 3M 7000048506 is a white, double-sided, pressure-sensitive closed-cell acrylic foam tape sold under the VHB Tape 4951 product line. At 45 mil thick, it delivers a firm bond with a PET film liner for clean handling and controlled application. The tape bonds effectively to high surface energy substrates and can be applied at temperatures as low as 32 degrees F, making it suitable for a wide range of job-site conditions. It provides cushioning, vibration damping, and impact resistance in addition to its primary bonding function. Supplied in a 0.75-inch-wide by 36-yard roll, it is used by tradespeople and fabricators who need a structural adhesive tape alternative.

VHB Tape 4951 is well suited for applications where mechanical fasteners are impractical or where surface aesthetics must be maintained. Common uses include bonding metal panels, attaching trim or nameplates, sealing joints in HVAC enclosures, and securing components in electrical or signage assemblies. The closed-cell foam core handles minor surface irregularities and helps maintain bond integrity under dynamic loads. It is used in both commercial construction and light industrial settings by HVAC sheet metal workers, electricians, sign installers, and general contractors.

Key Features

• 45 mil total thickness for gap-filling and cushioned bonding
• Double-sided pressure-sensitive adhesive bonds without primers on high surface energy substrates
• Closed-cell acrylic foam core provides vibration damping and impact resistance
• PET film liner for handling convenience and clean peel
• Application temperature down to 32 degrees F
• 0.75-inch-wide by 36-yard roll format for efficient coverage

Compatibility

Designed for bonding high surface energy substrates including metals, glass, and rigid plastics in commercial, industrial, and HVAC fabrication applications.

Installation Notes

Surface preparation is critical for maximum bond strength — clean surfaces thoroughly to remove oil, dust, and moisture before applying the tape. Apply firm, even pressure across the tape after placement to activate the adhesive. Allow adequate dwell time at room temperature before subjecting the bond to full load. Tape-based bonding methods should be evaluated against applicable building or equipment codes for structural applications.
