【Core Features】3M VHB Tape 4950 is a 1.1mm (45 mil) thick white double-sided acrylic foam tape. This heavy duty double sided mounting tape features a firm closed-cell foam core and general-purpose acrylic adhesive delivering high shear strength—up to 140 psi on stainless steel—with no curing required. Engineered with viscoelastic properties that absorb energy and distribute stress, it withstands long-term temperatures up to 200°F (93°C) and is designed to replace rivets, welds, and screws. Available in 1 inch width and other sizes for versatile applications.
【Superior Advantages】This 3M automotive double sided tape provides instant handling strength and develops a permanent, ultra-strong bond over time. The all-acrylic, closed-cell construction offers excellent UV, solvent, and moisture resistance for reliable indoor and outdoor performance. As a VHB double sided tape, it conforms well to uneven surfaces and bonds strongly to both high- and low-surface-energy materials, creating a seamless, virtually invisible connection. Perfect for automotive trim adhesive and car body panel applications.
【Customer Benefits】Achieve clean, smooth, and professional-looking bonds without drilling, welding, or messy liquid adhesives. This 3M double sided permanent tape heavy duty saves significant time and labor while providing design flexibility to join thinner, lighter, or dissimilar materials. The tape eliminates visible fasteners and surface damage, making it ideal for both permanent installations and projects where aesthetics matter. Strong enough to hold 5 pounds as heavy duty double sided mounting tape.
【Application Scenarios】Widely used in transportation, appliances, electronics, construction, signage, and general industry. Typical applications include automotive attaching emblems, nameplates, trim, and body side moldings. Perfect for securing LED light strips and signs, bonding automotive panels and interior components. Also ideal for mounting picture frames, mirrors, and power strips at home. Works as banner tape, red two sided tape alternative, and for clear glazing applications.
【Installation Guide】For optimal performance, clean surfaces thoroughly with a 5050 mix of isopropyl alcohol and water. Apply tape when temperatures are between 70°F and 100°F (21°C–38°C). After application, use a J-roller to apply firm pressure (at least 15 psi or 100 kPa). Bond strength reaches 50% in 20 minutes, 90% in 24 hours, and 100% in 72 hours. Avoid initial application on surfaces below 50°F (10°C). For challenging plastics, use Tape Primer 94 to enhance adhesion.
