The 3M Aerospace Sealant AC-770 is a Class B polysulfide sealant family, cured with manganese dioxide, designed for easy tooling. Its quick cure time and low density result in faster processing and lighter aircraft. These two-part sealants excel in resisting jet fuel, chemicals, and petroleum products prevalent in aerospace.

  • Lighter Sealant: Reduces weight by 3-4 lbs. per gallon compared to traditional options
  • Faster Curing: Enhances production efficiency
  • Cost Savings: Minimizes shrinkage and rework expenses
  • Fuselage Sealing: Effective in sealing joints and gaps in aircraft fuselages
  • Durable Bond: Maintains flexibility and strength under extreme conditions
