3M™ Aerospace Sealant AC-730 is a polysulfide fuselage sealant formulated for easy tooling. Our corrosion inhibitive, manganese dioxide cure product is highly resistant to aviation fuel and chemicals common to the aerospace industry. It provides an effective barrier against corrosion on aluminum and between dissimilar metals.

We engineered 3M™ Aerospace Sealant AC-730 specifically for fuselage applications, where it offers a number of advantages and benefits compared to traditional sealants. For starters, it is corrosion inhibitive yet contains no added chromate, which may help you comply with chromate reduction initiatives. AC-730 maintains flexibility and bond strength on aluminum, and between dissimilar metals under extremes of temperature, weathering and stress. Designed for easy tooling, it has outstanding resistance to jet fuel, chemicals and petroleum products common throughout the aerospace industry.
