3M 7000028869 Vhb Tape 4950 White 0.5in X 36yd 45 Mil

Product Description

The 3M 7000028869 is a double-sided, pressure-sensitive, closed-cell acrylic foam tape sold under the VHB Tape 4950 product line in white. At 45 mil thick, it delivers a firm bond with meaningful cushioning and vibration damping between bonded surfaces. A paper liner protects the adhesive until installation. This tape is designed to bond high surface energy substrates and is used across HVAC, electrical, and general construction applications where mechanical fasteners are not practical. Installers work with this product when assembling panels, securing nameplates, mounting gaskets, or attaching trim components in both indoor and outdoor environments.

VHB Tape 4950 is suited for residential and commercial trade applications where a clean, load-bearing adhesive bond is required. Common uses include attaching metal components, bonding plastics with high surface energy, and sealing or mounting in HVAC cabinet assembly, electrical enclosures, and panel fabrication. Each roll measures 0.5 inches wide by 36 yards long, providing substantial coverage per unit. The tape carries a UL listing under UL 746C, making it appropriate for use in applications requiring recognized flame and material performance standards.

Key Features

• 45 mil thickness provides firm bonding with integrated cushioning and impact resistance
• Double-sided, pressure-sensitive adhesive bonds on contact without additional curing equipment
• Closed-cell acrylic foam core delivers vibration damping and noise reduction between mated surfaces
• Paper liner protects adhesive during handling and allows clean, controlled application
• UL listing 746C recognized for flame and material performance requirements
• Bonds high surface energy substrates including metals, glass, and select plastics

Compatibility

Designed for use on high surface energy substrates including bare and coated metals, glass, and rigid plastics in residential and commercial HVAC, electrical, and construction assembly applications.

Installation Notes

Surface preparation is critical for maximum bond strength — clean bonding surfaces with an appropriate solvent to remove oils, dust, and contaminants before applying the tape. Apply firm, uniform pressure across the tape after placement to ensure full adhesive contact. Allow adequate dwell time at room temperature before applying load to the bond. This product is handled by sheet metal workers, HVAC technicians, and electricians during equipment assembly and panel mounting tasks.
