Our 3M Aerospace Sealant AC-770 is a family of Class B, manganese dioxide cured polysulfide sealants formulated for easy tooling. Their fast cure time and low density contribute to faster process times and lighter aircraft. These two-component sealants have outstanding resistance to jet fuel, chemicals and petroleum products common throughout the aerospace industry.
Lightweight, Effective Sealing
3M Aerospace Sealant AC-770 offers a number of advantages and benefits compared to competitive sealants. Its lighter weight formula, 25% lower density than traditional sealants, saves vital aircraft weight. AC-770 is available with a 1 hour and 2 hour application life and typical cure times of 6 hours and 11 hours, respectively. Its light weight and low density make it ideal for fuselage sealing and void filling applications. Our manganese dioxide cured product is also highly resistant to aviation fuel and many other chemicals common to the aerospace industry.
