3M 7000123670 Vhb Foam Tape 45 Mil 1 Inch X 36 Yd Gray

Product Description

The 3M 7000123670 is a gray, double-sided, closed-cell acrylic foam tape designed for permanent bonding applications across industrial, construction, and trade markets. At 45 mil thick, the foam core conforms to irregular and slightly textured surfaces, creating a durable, load-bearing bond without mechanical fasteners. A PE film liner protects the adhesive during handling and staging. The tape is plasticizer resistant, making it suitable for use with PVC and other plasticizer-emitting substrates. Installation requires no special tools beyond a roller or firm hand pressure to achieve full adhesive contact. This product carries a UL 746C listing, confirming suitability for use with polymeric materials in recognized applications.

This tape is used in residential and commercial construction, HVAC panel assembly, electrical enclosure fabrication, signage mounting, and general industrial bonding. It bonds effectively to high and medium surface energy substrates including painted metal, aluminum, glass, and many rigid plastics. The closed-cell foam construction also provides incidental cushioning, vibration damping, and impact resistance in assembled joints. It is typically applied by sheet metal workers, electricians, HVAC technicians, and general contractors where a clean, fastener-free bond line is required.

Key Features

• 45 mil closed-cell acrylic foam construction conforms to moderate surface irregularities
• Double-sided pressure-sensitive adhesive bonds without fasteners, rivets, or welding
• Plasticizer resistant for use with PVC and similar materials
• Provides cushioning, vibration damping, and impact resistance in bonded assemblies
• PE film liner protects adhesive face during storage and staged installation
• UL 746C listed for use with polymeric materials

Compatibility

Designed for bonding to high and medium surface energy substrates including painted metal, aluminum, glass, and rigid plastics. Performance on low surface energy plastics such as polyethylene or polypropylene is limited without surface preparation or primer.

Installation Notes

Surface preparation is critical for full bond strength — clean bonding surfaces thoroughly and allow to dry before application. Apply firm, uniform pressure across the full tape length immediately after positioning to initiate adhesive contact. Allow adequate dwell time before applying load to the bonded assembly. No mechanical fasteners or heat are required, but substrate temperature at time of application should be within the tape manufacturer's recommended range.
