3M 7000123926 Vhb Tape 4941 Gray 3in X 36yd 45 Mil

Product Description

The 3M 7000123926 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape sold under the VHB Tape 4941 product line in gray. At 45 mil thick, it delivers a conformable bond that adapts to irregular surfaces while providing cushioning, vibration damping, and impact resistance. The tape ships on a 3-inch-wide by 36-yard roll with a paper liner for handling convenience. Installers across HVAC, electrical, and general trade work rely on this tape when a durable, structural-grade adhesive bond is required without mechanical fasteners. The acrylic foam construction resists plasticizer migration, making it suitable for long-term contact with PVC and similar materials.

VHB Tape 4941 is designed for bonding high and medium surface energy substrates in both indoor and outdoor applications. Typical uses include panel mounting, gasket replacement, sign attachment, and sealing applications in commercial and industrial environments. The conformable foam core allows it to bridge minor surface gaps and contours. Tradespeople working on HVAC enclosures, electrical panels, and structural glazing commonly specify this tape where vibration resistance and a clean installation are priorities. The 3-inch width suits larger bonding surfaces that would be inefficient with narrower tape stock.

Key Features

• 45 mil closed-cell acrylic foam construction for conformable, gap-filling bonds
• Double-sided pressure-sensitive adhesive bonds high and medium surface energy substrates
• Plasticizer resistant for long-term compatibility with PVC and similar materials
• Provides cushioning, vibration damping, and impact resistance
• Paper liner for controlled application and handling convenience
• UL Listed under UL 746C

Compatibility

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

Installation Notes

Surface preparation is critical before applying VHB tape — clean surfaces with an appropriate solvent and allow to dry fully before application. Apply firm, uniform pressure across the entire bond area to activate the pressure-sensitive adhesive. Avoid stretching the tape during application, as this can reduce bond strength. Allow adequate dwell time at room temperature before subjecting the bond to shear or peel loads.
