Works on a Wide Variety of Similar and Dissimilar Substrates 3M™ Polyurethane Adhesive Sealant 550 Fast Cure (PDF, 371.52 Kb) is part of 3M 500 Series one-component, moisture-curing, urethane adhesives. These adhesives create a permanently elastic bond and bond strongly a variety of substrates such as wood, fiber reinforced plastic (FRP) and many other plastics to themselves, to metal and to glass. 3M moisture-curing formula cures by reacting with moisture in the air or the substrate. In addition to spraying, they can also be extruded from hand held or bench mounted applicators and are primarily dispensed with bulk application equipment. 3M one-part polyurethane adhesives work well for bonding a wide variety of plastics including polystyrene and polyacrylic. They are also effective on a wide variety of other substrates - from aluminum and glass to plastic and wood.
