Assembly & installation for aerospace

As a supplier to the aerospace industry for more than 70 years, 3M was among the first to introduce structural adhesives for aircraft. But our expertise in adhesives and sealants is just the start. We provide polyurethane protective tapes, structural adhesive films, polysulfide sealants and more, all designed to add efficiency and peace of mind for specific aircraft structural assembly processes. Our structural adhesive films deliver exceptional pre-bond humidity performance on composites. Polysulfide sealants are available in non-chromate corrosion inhibitive (NCCI) formulas, and feature low weight, fast curing and reduced shrinkage. Flyaway and temporary protective tapes are designed for specific needs, from impact and chafing to fluid resistance. There is more.
