3M - Aerospace AC-770 Class B Fuel Tank & Fuselage Sealant .
This 3M Aerospace Sealant (AC-770B) is a quick cure, low-density 2-component polysulfide fuselage sealant with superior resistance to jet fuel and aviation gasoline. It's also resistant to other petroleum products and chemicals that one commonly finds in aircraft-related fields. AC-770 Class B provides a flexible and strong bond on most metal, including titanium, steel, stainless steel, aluminum and various coatings in extreme temperatures and under various stress and weathering conditions. We have AC-770- B1 and AC-770-B2 available in 6 ounce sizes. This thixotropic paste compound can be applied by injection gun, extrusion or spatula and then tooled. Reduce shrinkage and the need for reworking with this advanced sealant.
