3M™ Polyurethane Adhesive Sealant 550FC is a moisture-curing sealant that forms flexible, weather-resistant bonds. This single-component adhesive bonds dissimilar materials including plastics, sheet molding compound, aluminum, steel, coated metal, stone and wood in temperatures ranging from -40 °F (-40 °C) to 194 °F (90 °C). Polyurethane sealants perform well in challenging industrial, transportation and construction settings by creating durable elastomeric bonds that seal against the elements. To keep the job moving, this fast-curing formula forms a paintable skin in only 60-90 minutes. High tensile strength, weather-resistance and short cure time allow 3M™ Polyurethane Adhesive Sealant 550FC to excel in applications such as exterior panel bonding, window framing and marine manufacturing.

• Multi-Surface Sealant: This moisture-curing adhesive sealant works on a wide variety of dissimilar substrates including wood, glass, stone, metal, polystyrene, polyacrylicand fiber reinforced plastics (FRP)
• Flexible Bonds: Its elastomeric polyurethane formula creates high-strength bonds that are ideal for a plethora of marine, transportationand construction applications
• Withstand The Elements: Seal hulls, windowsand door frames by forming a water-tight seal that can handle temperatures ranging from -40 °F (-40 °C) to 194 °F (90 °C)
• Fast Cure: Fast set and cure time increases productivity, forming a paintable skin in 60-90 minutes
• Easy to Use: One component adhesive for easy application with no mixing or guesswork
