What is 3m4930?
3m4930 is a high-performance double-sided adhesive tape made from acrylic foam, part of 3M’s VHB (Very High Bond) adhesive system. With a thickness of 0.64mm and white in color, it is designed for permanent bonding of high surface energy materials like metals, glass, and plastics. It delivers strong bonding strength, weather resistance, and conforms well to curved or irregular surfaces, making it suitable for diverse industrial applications.
