3M 7000142786 Vhb Acrylic Foam Tape 45 Mil 5/8in X 36yd Gray

Product Description

The 3M 7000142786 is a conformable, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a paper liner, sold in a 5/8-inch-wide by 36-yard roll. At 45 mil thick, it is designed for permanent bonding applications where conventional fasteners or liquid adhesives are not practical. The tape bonds to high and medium surface energy substrates and delivers cushioning, vibration damping, and impact resistance in a single-layer solution. It is plasticizer resistant, making it suitable for use with PVC and other plasticizer-bearing materials. Licensed to the UL 746C listing, this tape is used by contractors, maintenance technicians, and fabricators working in construction, signage, and industrial assembly applications.

This tape is suited for bonding metal, glass, painted surfaces, and many rigid plastics in both interior and exterior environments. Typical applications include attaching architectural panels, trim, and signage where the bond line must conform to surface irregularities and absorb differential thermal movement. The closed-cell foam core resists moisture ingress, making it a practical choice for outdoor or high-humidity installations. It is applied by hand with firm pressure contact and requires no curing equipment or mixing.

Key Features

• 45 mil total thickness provides a conformable bond layer with built-in cushioning and vibration damping
• Double-sided, pressure-sensitive acrylic foam construction bonds without fasteners or liquid adhesives
• Bonds to high and medium surface energy substrates including metals, glass, and rigid plastics
• Plasticizer resistant for compatibility with PVC and similar materials
• Closed-cell acrylic foam core resists moisture and environmental exposure
• UL 746C listed

Compatibility

Designed for bonding high and medium surface energy substrates including metal, glass, and painted or coated surfaces. No specific model or equipment compatibility is stated by the manufacturer for this SKU.

Installation Notes

Surface preparation is critical before application — clean bonding surfaces thoroughly to remove oils, dust, and loose material. Apply firm, even pressure across the full tape width to activate the pressure-sensitive adhesive. Allow dwell time for bond strength to develop before loading the joint. No special tools are required, but a roller or squeegee improves contact uniformity on flat substrates.
