3M 494112MM VHB Acrylic Foam Tape
3M™ VHB™ Tape 4941 is a versatile double-coated acrylic foam tape designed for permanent bonding applications. Its 0.045 inch thickness and conformable foam core allow it to bridge gaps and conform to irregular surfaces, providing excellent contact and adhesion. The multi-purpose acrylic adhesive bonds strongly to various substrates including metals, glass, and plastics. This tape is ideal for replacing mechanical fasteners like rivets and screws, eliminating the need for drilling, grinding, or welding. It also creates a durable seal against water and moisture, making it suitable for a wide range of industrial and commercial applications.
