3M 494119MM VHB Acrylic Foam Tape
3M™ VHB™ Tape 4941 is a 0.045 inch thick gray double-coated acrylic foam tape with a paper liner. It features multi-purpose acrylic adhesive on both sides, bonding effectively to a wide range of high and medium surface energy substrates. The conformable foam provides excellent contact between substrates, even when they have slight mismatches. This tape is ideal for replacing mechanical fasteners like rivets, screws, or liquid adhesives, creating a permanent seal against water and moisture. It's suitable for various industrial applications where strong, durable, and permanent bonding is required.
