Sealants

3M’s comprehensive line of polyurethane, silane modified polymer and marine adhesive sealants, sealant tapes and applicators define the industry standard for quality. Depend on us for bonding and sealing for all types of materials – wood, metal, glass, gelcoat, plastics and fiber-reinforced plastic.


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 are available in a wide variety of durometer, open time and colors to meet your application needs.

Silane-Modified Polymer Sealants

When UV stability and weatherability are most important, silane-modified polymer sealants (SMP) provide a strong and flexible bond that lasts. Their UV resistance is ideal for demanding exterior industrial and transportation applications where sunlight and weather exposure can be extreme. SMP sealants are available in a wide variety of durometer, open time and colors.

Marine Sealants

3M Marine Sealants designed specifically for lasting protection in harsh marine environments. Ideal for above and below the waterline applications. A broad range of marine sealants offer excellent UV and weather resistance for portholes and hull seams, screws and under moldings, as well as bonding for dissimilar materials, such as wood to fiberglass. Available in a variety of colors. With more than 50 years of reliable experience in this market, 3M Marine Sealants are the most trusted in the industry.
