3M 7100112661 Vhb Tape 4929 Black 1in X 72yd 25mil

Product Description

The 3M 7100112661 is a roll of 3M VHB Tape 4929 in black, a high-bond double-coated acrylic foam tape designed for permanent structural bonding without mechanical fasteners. The tape measures 1 inch wide by 72 yards long with a 25.0 mil total thickness. It delivers a conformable foam core that creates continuous contact across irregular or slightly textured surfaces, distributing stress loads across the full bond area. Licensed tradespeople and assembly technicians working in HVAC, electrical enclosure fabrication, and general construction applications use this tape for mounting, sealing, and joining rigid components where vibration resistance and weather sealing matter.

VHB Tape 4929 is suited for bonding metal, glass, high-surface-energy plastics, and painted surfaces in both interior and exterior applications. Its closed-cell acrylic foam construction resists moisture, solvents, and UV exposure, making it appropriate for outdoor signage attachment, panel bonding, and equipment mounting in commercial and light industrial settings. The black color blends with dark substrates and reduces visible adhesive at bond lines. Each case contains 9 rolls.

Key Features

• 25.0 mil total tape thickness for gap-filling conformability on uneven surfaces
• 1 inch width by 72 yards per roll for efficient coverage on linear bonding runs
• Double-coated acrylic foam construction bonds without rivets, screws, or welds
• Resistant to moisture, UV exposure, and common solvents for outdoor durability
• Black foam core minimizes adhesive visibility at bond edges
• Sold by the case, 9 rolls per case

Compatibility

Designed for structural bonding applications to high-surface-energy substrates including metals, glass, and painted surfaces in commercial and light industrial assembly; no specific model or equipment compatibility was stated in the product data.

Installation Notes

Surface preparation is critical for maximum bond strength — clean bonding surfaces thoroughly with isopropyl alcohol and allow to dry completely before application. Apply firm, even pressure across the full tape width after placement to ensure full contact between the adhesive and substrate. Allow adequate dwell time at room temperature before subjecting the bond to full load. No power systems need to be de-energized for tape installation, but follow all applicable site safety procedures when working on equipment panels or enclosures.
