Enabling lighter, safer and quieter aircraft that can be constructed faster, 3M designs and delivers a range of solutions for the aerospace industry.
AC-350 – 3M™ Aerospace Sealant AC-350 is a family of intermediate density, fast-curing, polysulfide fuel tank and fuselage sealants that provides outstanding resistance to aviation fuels and petroleum chemicals.
AC-380 – 3M™ Aerospace Sealant AC-380 is a family of Class B polysulfide sealants formulated for easy tooling. This family of sealants saves time through its fast cure and saves weight through its low density formula.
AC-735 – 3M™ AC-735 is specifically engineered for fuselage applications. It is corrosion inhibitive yet contains no added chromate. It has a 25% lower density than traditional sealants yet maintains flexibility and bond strength under adverse conditions on aluminium, titanium, steel, stainless steel and composites.
