3M 7010334342 Vhb Foam Tape 45 Mil 2in X 36yd Gray

Product Description

The 3M 7010334342 is a gray, double-sided, closed-cell acrylic foam tape in the VHB 4941 series, measuring 2 inches wide by 36 yards long at 45 mil thickness. It is a conformable, pressure-sensitive tape with a paper liner designed for structural and semi-structural bonding applications across industrial, construction, and trade assembly work. The acrylic foam core provides cushioning, vibration damping, and impact resistance while maintaining a strong, lasting bond on high and medium surface energy substrates. It carries a UL 746C listing, confirming suitability for use with plastic components.

This tape is used where mechanical fasteners or liquid adhesives are impractical. Common applications include bonding metal panels, attaching trim and nameplates, mounting signage, and sealing or joining dissimilar materials in HVAC enclosure assembly, electrical panel fabrication, and general industrial or construction trades. Its plasticizer resistance makes it suitable for long-term contact with PVC and other plasticizer-containing substrates. The tape is sold by the roll and is suited for both shop and field use.

Key Features

• 45 mil closed-cell acrylic foam construction for conformability and gap-filling
• Double-sided pressure-sensitive adhesive bonds high and medium surface energy substrates
• Provides cushioning, vibration damping, and impact resistance in bonded joints
• Plasticizer resistant for compatibility with PVC and similar materials
• UL 746C listed for use with plastic components
• Paper liner for clean, controlled application

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and select plastics. Suitable for use in applications requiring UL 746C compliance for plastic component bonding.

Installation Notes

Surface preparation is critical before application — clean bonding surfaces thoroughly to remove oil, dust, and moisture for maximum adhesion. Apply firm, even pressure across the full tape surface after positioning to ensure full contact adhesive transfer. This tape is intended for permanent bonding; removal after cure may damage substrates. Follow applicable local building and safety codes when using adhesive systems in structural or load-bearing applications.
