3M’s comprehensive range of adhesives, sealants and tapes offers the rail industry both internal and external joint design solutions for structurally bonding and sealing components. These solutions can also reduce weight, noise, vibration, cost and improve productivity by removing the requirement for mechanical fasteners (screws, bolts, rivets, etc) and their associated preparation (drilling/punching holes, assembly tools, etc.) They can also replace welding and the refinishing work frequently required to provide an aesthetic surface finish after welding.
