These solutions represent the 70-plus years that 3M has spent developing better ways to work in the aerospace industry. We are experts at bonding to metals, protecting them from corrosion and helping prepare them for coatings and paint. We have continually pioneered the development of polysulfide sealant technology for lighter weight, easier shop handling and minimal shrinkage. A wide range of adhesives is designed specifically for bonding to metal and painted metal. They are available in a broad range of service and cure temperatures. You’ll also find non-chromated surface pre-treatments for aluminum alloys, stainless steel and titanium, and water-based and NCCI primers that promote long-term bonding after surface prep.
Choose an adhesive film designed for bonding metal-to-metal and metal-to-honeycomb structures, at the right cure temperatures for your application.
With a wide range of curing temps, these thermally expanding adhesives can help streamline production and eliminate rework.
Ultra-thin and compact, 3M™ Friction Shims get their strong "grip" from embedded diamonds. They enhance friction and reliably managing high sheer forces in critical joints of airplane structures. 3M friction shims also help you protect bolted connections against potential joint failure that can be caused by loosening or fatigue.
Available with a work life as little as 20 minutes, our 3M™ Scotch-Weld™ urethane and epoxy paste adhesives are toughened for metal-to-metal bonding. Not sure what you're looking for? Use the chart below to help you identify the best product for your needs.

Solvent- and water based, chromated and non-chromated heat-cure primers inhibit corrosion on prepared metal parts and maximize adhesive wet out.
