description

• 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.

features
