Works on a Wide Variety of Similar and Dissimilar Substrates
3M™ Polyurethane Adhesive Sealant 550 Fast Cure is part of our 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. Our 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_. Our 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 -40?F/-40?C to 194?F/90?C. 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. Polyurethane sealants are available in a wide variety of Shore A hardness, open time and colors to meet many application needs. Choose a 3M Manual or Pneumatic Applicator for dispensing 3M adhesives sealant cartridges and 400ml/600ml sausage packs.
