3M VHB Tape 4950 is a double-sided tape comprised of a general-purpose acrylic adhesive with a firm, foam core that delivers a total thickness of 45 mil (1.1 mm) when applied and requires no fixturing or curing time. Engineered to be strong, it can replace rivets, welds, and screws while providing faster production by eliminating the need for drilling, welding, grinding, and project cleanup. Offering seamless joining and minimal surface preparation, this easy-to-use bonding method keeps surfaces smooth and enhances the appearance of applications involving thin, lightweight, and dissimilar materials. Providing adhesion to a broad range of materials from metals, glass, and other high surface energy substrates, the advanced closed-cell acrylic technology provides secure bonding that protects against water and seals tightly for long-term durability. It performs in applications for short-term use (up to four hours) at a temperature up to 300 Degree F (149 Degree C) or long-term use withstanding up to 200 Degree F (93 Degree C). These attributes make 3M VHB Tape 4950 a reliable choice to take on a variety of bonding and sealing applications in transportation, signage, displays, general industrial, appliance, and electronics. Discover the many ways to apply the powerful bonding potential of 3M VHB Tape 4950.
