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.
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.
3M™ Weatherban™ Sealants keep weather out and prevent fluid migration with no curing. These permanently tacky butyl tapes provide gasket-like watertight seals around openings and can also seal seams.
3M™ Weatherban™ Ribbon Sealant PF5423
Large surfaces often require sealants to be flexible and UV resistant. We have adhesive sealants for these and other situations, including chemical exposure (fuel, detergents), sealing metal, bonding wood and more.
3M™ Scotch-Seal™ Industrial Sealant 800
3M™ Weatherban™ Acrylic Sealant 606NF
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:
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.
For industries that require Flame, Smoke and Toxicity (FST) Testing, we have test results searchable by product name or by test standard at 3M.com/Rail/FST.
