3M 7100109198 Vhb Double-sided Foam Tape 3/4in X 36yd Gray

Product Description

The 3M 7100109198 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape designed for high-strength bonding in industrial and trade applications. At 62 mil thick, this tape delivers firm, consistent adhesion to high surface energy substrates including metals, composites, and coated surfaces. The gray PE film liner protects the adhesive until installation. It is well suited for applications where conventional fasteners or liquid adhesives are impractical. HVAC fabricators, sheet metal contractors, electrical enclosure assemblers, and industrial maintenance technicians are the primary installers of this product.

This tape is commonly used to bond metal parts prior to paint processing, making it a practical choice in fabrication shops and manufacturing environments. Its closed-cell acrylic foam core provides cushioning, vibration damping, and impact resistance alongside the adhesive bond. The tape is available in a 3/4 inch width on a 36-yard roll, making it a good fit for linear seaming, panel attachment, and trim bonding tasks where a narrow, continuous bond line is needed. UL listing 746C confirms its suitability for component bonding in temperature-rated assemblies.

Key Features

• 62 mil closed-cell acrylic foam construction provides firm, gap-filling adhesion
• Bonds high surface energy substrates including metals and coated panels
• Excellent temperature resistance for use in heat-exposed assemblies
• Suitable for bonding metal parts prior to paint processing
• Provides cushioning, damping, and impact resistance in the bond line
• UL listing 746C for component bonding in rated assemblies

Compatibility

Designed for bonding high surface energy substrates such as metals, glass, and high-energy plastics in industrial fabrication, HVAC assembly, and general maintenance applications.

Installation Notes

Surface preparation is critical for maximum bond strength — clean bonding surfaces thoroughly to remove oils, dust, and contaminants before application. Apply firm, even pressure across the tape after positioning to ensure full contact adhesion. Allow adequate dwell time at room temperature before subjecting the bond to full load. Removal of the PE film liner just before bonding helps prevent adhesive contamination.
