3M 7000123398 Vhb Foam Tape 45 Mil 1 in X 36 Yd Black

Product Description

The 3M 7000123398 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape designed for high-strength bonding applications. At 45 mil thick, this VHB tape delivers a firm, conformable bond layer that also provides cushioning, vibration damping, and impact resistance. The tape ships in a 1-inch-wide by 36-yard roll with a paper liner for handling convenience. It is used by contractors, fabricators, maintenance technicians, and assembly professionals who need a solvent-free structural bonding method on high surface energy substrates such as metals, glass, and many plastics.

This tape is suited for both indoor and outdoor bonding tasks where mechanical fasteners are impractical or undesirable. Common applications include panel attachment, sign mounting, gasket bonding, and equipment assembly in commercial and industrial environments. The closed-cell acrylic foam core resists moisture, UV exposure, and temperature cycling, making it a reliable choice for permanent installations. The paper liner allows clean dispensing and precise placement during application.

Key Features

• 45 mil total thickness provides a substantial bond layer with built-in cushioning
• Double-sided, pressure-sensitive design eliminates the need for mechanical fasteners
• Closed-cell acrylic foam core resists moisture, UV, and temperature variation
• Bonds to high surface energy substrates including metals, glass, and compatible plastics
• Paper liner supports controlled application and clean dispensing
• 1-inch width by 36-yard length provides ample coverage per roll

Compatibility

Designed for bonding high surface energy substrates in industrial, commercial, and construction assembly applications. Verify substrate compatibility and surface preparation requirements before use.

Installation Notes

Surface preparation is critical for maximum bond strength — clean substrate surfaces thoroughly to remove oils, dust, and contaminants before applying the tape. Apply firm, even pressure across the full bonded area to ensure full contact adhesion. Allow adequate dwell time at room temperature before subjecting the bond to stress loads. This product is intended for professional or experienced use; follow all applicable safety data sheet guidance when working in confined or poorly ventilated areas.
