3M 7000028996 Vhb Tape 4991 Gray 0.5in X 36yd 91 Mil

Product Description

The 3M 7000028996 is a conformable, double-sided, pressure-sensitive, closed-cell acrylic foam tape sold in a 0.5-inch-wide by 36-yard roll at 91 mil thickness. The tape features a PE film liner for handling convenience and bonds effectively to high and medium surface energy substrates. Its foam construction provides cushioning, vibration damping, and impact resistance across a wide range of industrial and construction applications. The acrylic adhesive system is plasticizer resistant, making it suitable for use with PVC and other plasticizer-bearing materials over time. This tape carries a UL 746C listing, confirming suitability for use with polymeric materials in evaluated applications.

VHB Tape 4991 is used in industrial assembly, panel bonding, sign mounting, glazing applications, and architectural fabrication where a permanent, high-strength bond is required without mechanical fasteners. The gray color and conformable foam core allow it to conform to slightly irregular or curved surfaces. It is commonly specified by contractors, glaziers, fabricators, and maintenance technicians working with metals, composites, glass, and coated substrates in both commercial and industrial environments.

Key Features

• 91 mil closed-cell acrylic foam core provides cushioning and vibration damping
• Double-sided pressure-sensitive adhesive bonds high and medium surface energy substrates
• Plasticizer resistant — compatible with PVC and similar materials over extended service
• PE film liner for clean, controlled application
• UL 746C listed for use with polymeric materials
• Conformable construction suits curved and irregular bonding surfaces

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and composites in industrial and construction assembly applications.

Installation Notes

Surface preparation is critical — clean bonding surfaces with an appropriate solvent cleaner and allow to dry completely before applying tape. Apply firm pressure across the full bond area to ensure full adhesive contact; a roller is recommended. Avoid stretching the tape during application, as this reduces effective bond area. Allow adequate dwell time at room temperature before loading the bond joint.
