3M 7000123671 Vhb Foam Tape 25 Mil 0.5in X 72yd Gray

Product Description

The 3M 7000123671 is a gray, double-sided, closed-cell acrylic foam tape designed for permanent bonding to high and medium surface energy substrates. At 25 mil thick, the conformable foam core provides cushioning, vibration damping, and impact resistance alongside a strong pressure-sensitive adhesive bond. A paper liner protects the adhesive until application. The tape carries a UL 746C listing, making it suitable for use in assemblies where material flammability and performance standards must be documented. Fabricators, glaziers, sign installers, and industrial maintenance technicians are the typical end users for this product.

This tape is used in applications where mechanical fasteners or liquid adhesives are impractical. Common install scenarios include bonding architectural panels, attaching nameplates and trim, mounting foam gaskets, and assembling components in transportation, HVAC, and industrial equipment. Each roll measures 0.5 inches wide by 72 yards long, delivering substantial coverage per unit. The closed-cell foam construction resists plasticizer migration, making it compatible with PVC and other plasticizer-containing materials without adhesive degradation over time.

Key Features

• 25 mil closed-cell acrylic foam core provides cushioning, damping, and impact resistance
• Double-sided pressure-sensitive adhesive bonds high and medium surface energy substrates
• Plasticizer resistant — compatible with PVC and similar materials
• UL 746C listed for assemblies requiring documented flammability and performance ratings
• Paper liner for clean handling and precise application
• 0.5 inches x 72 yards per roll for high-coverage installations

Compatibility

Designed for bonding to high and medium surface energy substrates including metals, glass, and many rigid plastics. Not intended for low surface energy substrates such as untreated polyethylene or polypropylene without surface preparation.

Installation Notes

Surface preparation is critical — clean bonding surfaces of oil, dust, and loose particles before application. Apply firm, even pressure across the full tape width to achieve maximum adhesive contact. Allow adequate dwell time at room temperature before placing the assembly under load. This product is typically applied by fabricators or installers working under standard workshop or field conditions; follow all applicable safety data sheet guidance when handling adhesive products.
