3M™ VHB™ Tape 4949 is a black, double-sided tape made of a general-purpose acrylic adhesive and a firm, foam core that delivers a total thickness of 45 mil (1.1 mm) when applied and requires no time for curing. Designed to bond a variety of high surface energy (HSE) substrates, this easy-to-use method can help increase productivity by eliminating steps, such as drilling, welding, and other finishing work. Because of its high-strength performance, the tape bonds thin, dissimilar, and lightweight materials while offering a smooth and seamless alternative to using rivets, welds, fasteners, and screws. The advanced closed-cell acrylic technology provides secure bonding that protects against water and seals tightly. It performs in applications for short-term use at a temperature up to 300 °F (149 °C) or long-term use withstanding up to 200 °F (93 °C). This tape offers an excellent balance of strength, viscoelasticity, and adhesion, making it a powerful bonding solution across numerous industries, including window and door assembly, signage, electronics, construction, and general industrial. Explore the versatility and durability of 3M™ VHB™ Tape 4949 for your next operation.
