3M 560 Polyurethane Sealant Adhesive (various variants)

3M™ 560 is a single-component, moisture-curing polyurethane adhesive sealant, designed for high mechanical strength and durability in demanding conditions. It performs excellently in panel bonding and joining a wide range of materials, such as plastics, coated metals, aluminum, steel, and wood. It can successfully replace rivets or other mechanical fasteners. The product is available in grey (310 ml) and black (600 ml).

Benefits and Properties

✅ Very high bonding strength – an ideal alternative to rivets and mechanical fasteners
✅ Good UV and moisture resistance – retains properties in outdoor conditions
✅ Gap-filling capability – compensates for material movements and differing thermal expansions
✅ Medium Shore A hardness – provides a balance between flexibility and durability
✅ Paintable – after skin formation for an aesthetic finish
✅ No primer required in most applications – fast and easy application

Application Tips

Before application, ensure surfaces are clean, dry, and degreased. Apply using a standard cartridge or tube gun. After a skin forms (50–60 minutes), the surface can be painted. For best results, press evenly to achieve optimal bond strength.
