3M 7000048891 Vhb Acrylic Foam Tape 4611 Gray 45 Mil

Product Description

The 3M 7000048891 is a double-sided acrylic foam tape sold under the 3M VHB (Very High Bond) tape line, model 4611. It carries a gray-colored foam core at 45 mil thickness and comes in a roll measuring 3/4 inch wide by 36 yards long. The acrylic foam construction delivers a conformable, high-strength bond to a wide range of surfaces including metals, glass, and many plastics. It is used by trade professionals in HVAC, electrical, and general construction applications where a durable, solvent-resistant adhesive bond is needed in place of mechanical fasteners or liquid adhesives. Each roll is sold as a single unit.

This tape is suited for bonding trim, panels, gaskets, and nameplates in both residential and light commercial settings. Common applications include attaching metal junction box covers, securing foam insulation edges, bonding decorative trim to metal enclosures, and sealing light-duty gaps. The 45 mil foam thickness allows the tape to conform to slightly uneven surfaces, maintaining contact across the bond area. It is a practical replacement for rivets, screws, or welds in non-structural, surface-mounting applications.

Key Features

• 45 mil foam thickness for conformability on mildly irregular surfaces
• Double-sided acrylic adhesive on both faces for substrate-to-substrate bonding
• Gray foam core for neutral appearance at bond lines
• Roll format: 3/4 inch wide by 36 yards — suitable for high-volume or repetitive bonding tasks
• Acrylic foam construction resists solvents, UV exposure, and moisture over time

Compatibility

Designed as an OEM-style replacement or direct-use bonding tape for trade applications requiring a high-strength double-sided foam tape in the 45 mil thickness range.

Installation Notes

Surface preparation is critical — clean bonding surfaces thoroughly with an appropriate solvent wipe and allow to dry completely before applying tape. Apply firm, even pressure across the full bond area to ensure full adhesive contact. This tape is intended for permanent bonding; removal after cure may damage the substrate surface. Follow applicable building and mechanical codes when substituting tape bonding for mechanical fasteners in any structural or load-bearing application.
