3M 7000123924 Vhb Acrylic Foam Tape 4611 Gray 45 Mil 1x36yd

Product Description

The 3M 7000123924 is a double-sided acrylic foam tape sold under the 3M VHB 4611 series. It delivers a permanent, high-strength bond without mechanical fasteners, rivets, or welds. The tape is gray in color, 45 mil thick, and comes in a 1-inch-wide by 36-yard roll. The closed-cell acrylic foam core conforms to surface irregularities and provides continuous stress distribution across the bond line. It is commonly installed by sheet metal fabricators, HVAC equipment assemblers, electricians, and sign and glazing contractors who need a structural adhesive solution in tight or finished assemblies.

This tape is suited for bonding metal panels, plastic trim, nameplates, gaskets, and similar components in both indoor and outdoor applications. The 45 mil gauge provides enough compliance to accommodate surface contour variations and thermal expansion. It is commonly used in HVAC cabinet assembly, electrical enclosure sealing, and light commercial panel fabrication where a clean, fastener-free finish is required. Each unit is a single roll; the case pack is 9 rolls.

Key Features

• Double-sided acrylic foam construction provides a permanent structural bond without fasteners
• 45 mil gauge thickness accommodates surface contours and thermal movement
• 1-inch width by 36-yard length per roll for consistent coverage on long runs
• Gray color blends with metal and painted surfaces common in trade applications
• Closed-cell foam core resists moisture and maintains adhesion in varied environments

Compatibility

Designed for use in applications requiring a high-strength double-sided foam tape bond on metal, painted metal, glass, and rigid plastic substrates typical in HVAC, electrical, and light fabrication work.

Installation Notes

Surface preparation is critical — clean and dry all bonding surfaces before application to remove oils, dust, and contaminants. Apply firm, even pressure across the full tape length after placement to ensure full contact between the adhesive and substrate. Allow adequate dwell time before loading the bond joint, as acrylic foam adhesives build strength over 24 to 72 hours. No special tools or licensed trade certification is required, but structural bonding applications should be reviewed against applicable building or equipment codes.
