VHB VHB-4910F (25-mm-Roll)

3M™ VHB™ Tape 4910 Clear Acrylic Foam Bonding Tape

Overview

3M™ VHB™ Tape 4910 is a transparent, double-coated acrylic foam bonding tape designed for permanent structural bonding where a virtually invisible bond line is required. Featuring a clear, solid acrylic foam core with general-purpose acrylic adhesive on both sides, it delivers excellent adhesion to high surface energy substrates including glass, metals and clear plastics. It replaces mechanical fasteners, rivets and liquid adhesives in many industrial and architectural applications while providing exceptional durability, weather resistance and long-term performance.
