Polyurethane Adhesive Takes on Mechanical Fasteners

3M says that its Polyurethane Adhesive Sealant 560 is an improvement on traditional fasteners and can be used for bonding in trucks, trailers, and trains. The company reminds its clients that mechanical fasteners require holes to be drilled in the substrates, weakening them and potentially leaving them vulnerable to corrosion. Stress is also concentrated at the fastener instead of being spread over a wider area, and the appearance of rivets, bolts or screws can spoil the overall appearance and finish.

By contrast, 3M says its adhesive allows for a neat finish, stronger bonds, high impact resistance and high corrosion resistance with the added benefits of elasticity combined with high tensile strength. The company says the product also solves the problem of bonding dissimilar substrates, allowing designers greater freedom in their choice of materials.

3M reports that its Polyurethane Adhesive Sealant is UV resistant, bonds to metals, plastics, fiberglass, and wood, and is available in white, grey, or black.
