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

  • MULTI-SURFACE SEALANT: This moisture-curing adhesive sealant works on a wide variety of dissimilar substrates including wood, glass, stone, metal, polystyrene, polyacrylic, and fiber reinforced plastics (FRP)
  • FLEXIBLE BONDS: Its elastomeric polyurethane formula creates high-strength bonds that are ideal for a plethora of marine, transportation, and construction applications
  • WITHSTAND THE ELEMENTS: Seal hulls, windows, and 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

Works on a Wide Variety of Similar and Dissimilar Substrates

3M Polyurethane Adhesive Sealant 550 Fast Cure is part of the 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. The 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. These 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.

Recommended Applications
  • Marine deck to hull bonding
  • Vertical and horizontal expansion joint applications
  • Concrete and masonry control joints
  • Aluminum curtain wall and storefronts
  • Door and window frame perimeters
Paintable after Skin Forms for Improved Appearance

3M Polyurethane Adhesive Sealant 550 offers an alternative to mechanical fasteners and can replace rivets in some applications. It will bond dissimilar substrates and a wide selection of materials. This adhesive will perform in temperatures ranging from -40F/-40C to 194F/90C. Once skin forms (60-90 minutes), the sealant can be painted to improve the final finish.

Understanding Polyurethane Sealants

Polyurethane sealants provide strong, flexible durable elastomeric bonds that seal against the elements. These sealants excel in challenging industrial, transportation and construction applications.
