3M™ VHB™ Tape 4941 is a high-performance double-sided acrylic foam tape designed for permanent bonding of metals, glass, plastics, and painted surfaces. Featuring a multi-purpose acrylic adhesive and conformable foam core, it provides an excellent balance of strength and flexibility.
This tape bonds to a broad range of high and medium surface energy materials, including plastics, paints, and even plasticized vinyl—making it one of the most versatile VHB tapes available.
With a 45 mil (1.1 mm) thickness, it offers strong gap-filling capability while maintaining consistent adhesion across slightly irregular surfaces. It is widely used to replace rivets, screws, and welds, delivering a clean, professional finish while reducing assembly time.
