3M™ 4950 VHB™ Tape is a 45-mil white acrylic foam tape with acrylic adhesive on both sides, delivering a permanent, structural-grade bond capable of replacing mechanical fasteners such as rivets, screws, spot welds, and liquid adhesives. The firm foam core provides conformability alongside load-bearing strength, and UL746C listing confirms its suitability for demanding assembly applications.

This tape is used in industrial manufacturing, architectural glazing, sign fabrication, transportation assembly, and commercial construction. It bonds reliably to aluminum, steel, glass, painted surfaces, and composite substrates — making it a practical fastener alternative wherever surface aesthetics or weight reduction are priorities.

The 45-mil construction includes a kraft paper liner that protects the adhesive until application. The tape resists moisture, solvents, and UV exposure and maintains performance from -40°F to 200°F. Each roll measures 1 inch wide by 5 yards long and weighs 0.36 lbs. Ships via parcel.
