It provides excellent adhesion to various materials such as concrete, wood, aluminum, most lacquered metals, polyester, glass, and stone. This versatile formula is suitable for both above and below the waterline in marine applications and bonding aluminum, FRP, metal, plastic, SMC, steel, and wood.

Recommended Applications
  • Cosmetic skinning on boats, buses, trailers
  • Bonding high-performance applications, such as marine windshields
  • Waterproofing joints without primers in concrete, glass, marble, granite, and brick
  • Bonding and waterproofing modular building panels or bathroom units
Paintable after Skin Forms for Improved Appearance

3M™ Polyurethane Adhesive Sealant 551 can replace rivets in some applications and offers an alternative to mechanical fasteners. It bonds dissimilar substrates and a wide selection of materials. This adhesive can 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, and 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 adhesive sealant cartridges and 400ml/600ml sausage packs.
