3M 7000123345 Vhb Foam Bonding Tape 1 in X 72 Yd 25 Mil

Product Description

The 3M 7000123345 is a white VHB acrylic foam bonding tape designed for high-strength permanent adhesion in demanding assembly and mounting applications. Built on an acrylic foam backing with an acrylic adhesive system, it delivers a VHB-rated bond strength of 20 lb/in and handles maximum operating temperatures up to 200 degrees F. At 25 mil thick, this tape is engineered for applications where gap-filling and conformability are required to achieve full surface contact. Each roll measures 1 inch wide by 72 yards long. Sold 9 rolls per case.

This tape is suited for metal-to-metal bonding, panel attachment, sign mounting, and structural assembly in commercial, industrial, and construction environments. The 25 mil thickness makes it particularly effective on surfaces with minor irregularities, where a thinner tape would fail to maintain consistent contact. HVAC sheet metal fabricators, electrical enclosure assemblers, and glazing contractors commonly use this product as a mechanical fastener replacement or supplemental bonding agent. Its white color is appropriate for visible edges in architectural or signage applications.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-use bonding tape for applications requiring high-strength acrylic foam adhesive tape with a 1 inch width and 25 mil thickness profile.

Installation Notes

Surface preparation is critical — clean bonding surfaces thoroughly with isopropyl alcohol and allow to dry completely before application. Apply firm, even pressure across the full tape length to ensure full adhesive contact; a roller tool is recommended. This tape creates a permanent bond; repositioning after contact is not possible. Consult applicable building or assembly codes when using as a structural fastener replacement.
