What is 3m4920?
3m4920 is a high-performance VHB (Very High Bond) acrylic foam double-sided adhesive tape designed for reliable bonding across a wide range of surfaces. With a thickness of 0.4mm and a white foam backing, it offers strong adhesion to materials like metals, plastics, and glass. Its flexibility, UV resistance, and shear strength make it suitable for both indoor and outdoor use, particularly in applications requiring a clean appearance and long-lasting bond.
