3M 7000028870 Vhb Tape 4950 White 0.75in X 36yd 45 Mil

Product Description

The 3M 7000028870 is a white VHB (Very High Bond) double-coated acrylic foam tape in the 4950 series, measuring 0.75 inches wide by 36 yards long with a 45 mil gauge. VHB tape in this series is engineered for high-strength structural bonding without mechanical fasteners. The acrylic foam core conforms to irregular surfaces and maintains adhesion across a wide temperature range. This product is sold by the case, with 12 rolls per case, at a total case weight of 17.46 pounds. Installers in HVAC, electrical, and general construction trades use this tape for panel attachment, gasket bonding, and vibration-dampening applications where screws or rivets are not practical.

The 4950 series VHB tape is suited for bonding metal, glass, and high-surface-energy plastics in both residential and commercial applications. Typical install scenarios include HVAC enclosure assembly, sign mounting, electrical panel trim attachment, and interior architectural bonding. The white color makes it appropriate for visible or finished-surface applications where tape color may be a factor. This tape is packaged 12 rolls per case for job-site and shop stocking.

Key Features

• 45 mil gauge acrylic foam core for conformability and load distribution
• 0.75 inches wide by 36 yards per roll for consistent coverage
• White facing suitable for finished or visible surface applications
• High-strength bonding without drilling or mechanical fasteners
• 12 rolls per case for bulk stocking efficiency

Compatibility

Designed for structural and semi-structural bonding to metal, glass, and high-surface-energy plastic substrates in commercial and residential trade applications.

Installation Notes

Surface preparation is critical for VHB adhesion — clean bonding surfaces with an appropriate solvent cleaner and allow to dry fully before application. Apply firm, uniform pressure across the tape length to ensure full contact; a roller is recommended. Follow manufacturer surface preparation guidelines and allow adequate dwell time before applying load to the bond. No power disconnect is required for tape-only applications, but follow applicable safety protocols when working near energized equipment.
