    3M™ Polyurethane Sealants

    3M™ Polyurethane Sealants provide a strong, flexible and durable elastomeric bond that seals against the elements. They excel in challenging industrial, transportation and construction applications and can be painted once a skin forms. These sealants are available in a wide variety of hardnesses, open times and colors to meet your application needs.

    3M™ Silane-Modified Polymer Sealants

    When UV stability and weatherability are most important, silane-modified polymer (SMP) sealants provide a strong and flexible bond that lasts. The UV resistance of SMPs is ideal for demanding exterior industrial and transportation applications where sunlight and weather exposure can be extreme. These sealants are isocyanate-free, immediately paintable and available in a wide variety of hardnesses, open times and colors to meet your application needs.

  • Benefits of 3M™ Adhesive Sealants

    3M offers a comprehensive line of adhesive sealants and sealant tapes that help define the industry standard for quality. Whatever you’re bonding and sealing – wood, metal, glass, gelcoat, plastics or fiber-reinforced plastic – 3M has sealants with the characteristics you need:
     

    • Gap Filling for rough, patterned or uneven substrates
    • Strength for bonds that need to hold firm as well as seal
    • Durability to stand up to tough environments such as weather, saltwater or UV
    • Flexibility to allow joint movement while maintaining a bond
    • Sealing to keep outside environments out and inside things in

Application Methods

Your application method will depend on your unique circumstances. Generally speaking, manual application involves little investment in equipment but with higher labor costs while automated application requires little or no labor but has high equipment outlays up front. Machine-assisted application falls between those extremes: a trained operator uses a hand-held applicator to apply the adhesive, which is forced out with the aid of a battery or pneumatic system.
