3M 7000028909 Vhb Tape 4941F Gray 0.5in X 36yd 45mil

Product Description

The 3M 7000028909 is a gray, double-sided, closed-cell acrylic foam tape sold under the 3M VHB Tape 4941F designation. It measures 0.5 inches wide by 36 yards long and carries a thickness of 45 mil. A PE film liner protects the adhesive until application. The tape is pressure-sensitive and conformable, making it well suited for bonding irregular or slightly curved surfaces. It provides cushioning, vibration damping, and impact resistance in addition to a strong permanent bond. The acrylic foam construction is plasticizer resistant, making it appropriate for long-term assemblies where plasticizer migration from substrates such as PVC is a concern. Licensed trades and industrial assembly technicians are the primary installers.

This tape is designed for bonding high and medium surface energy substrates including metals, glass, and many plastics. Typical applications include panel attachment, sign mounting, architectural glazing, equipment assembly, and any installation where mechanical fasteners are undesirable or impractical. The 0.5-inch width and 36-yard roll length make this a small-pack format suited for detail work, field repairs, or low-volume assembly operations. The UL 746C listing supports use in applications requiring recognized component compliance for polymeric materials.

Key Features

• 45 mil thick closed-cell acrylic foam core for conformability and gap-filling
• Double-sided pressure-sensitive adhesive bonds without mechanical fasteners
• Plasticizer resistant construction for durable bonding to PVC and similar substrates
• Provides cushioning, vibration damping, and impact resistance in assembled joints
• PE film liner for clean handling and controlled application
• UL 746C listed for polymeric material compliance

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and select plastics. Suitable for use in applications requiring UL 746C recognized component compliance.

Installation Notes

Surface preparation is critical before applying VHB tape. Clean and dry the bonding surface thoroughly, removing oils, dust, and loose material. Apply firm, even pressure across the tape after placement to ensure full adhesive contact. Allow adequate dwell time before loading the bond per the assembly requirements. Do not stretch the tape during application as this can reduce long-term bond strength.
