3M™ Aerospace Sealant AC-380 is a family of Class B polysulfide sealants formulated for easy tooling. Their quick cure and low density contribute to faster process times and less weight. These two-component, manganese dioxide cure sealants have outstanding resistance to aviation gasoline, jet fuel and chemical products common to the aerospace industry.

3M™ Aerospace Sealant AC-380 offers a number of advantages and benefits compared to traditional sealants. We designed this family of sealants to save time through its fast cure and save weight through its low density formula. Our manganese dioxide cure product is also highly resistant to aviation fuel and many chemicals common to the aircraft industry, making it ideal for fuel tank and fuselage sealing applications.
