3M™ Aerospace Sealant AC-360 is a family of intermediate density, manganese dioxide cured, polysulfide fuel tank sealants that cure rapidly and provide outstanding resistance to aviation fuels and petroleum chemicals. Our Class A and B variants maintain bond strength on many metal, composite and coated substrates and help meet a range of applications for integral fuel tank and fuselage sealing.
AC-360 is 15% lighter than conventional fuel tank sealants
The 3M™ Aerospace Sealant AC-360 family of manganese dioxide cured polysulfide sealants provides a number of advantages and benefits compared to traditional sealants. Two classes, multiple work lives and rapid cure times help meet a wide range of manufacturing and maintenance needs.
When our Class A version is mixed, it provides a smooth pourable liquid that spreads evenly with a brush or roller to cover large areas quickly. Available with a two hour work life, 3M™ Aerospace Sealant AC-360 Class A gives you ample time for application while its rapid cure keeps your processes moving forward.
Our Class B version mixes to a thixotropic paste that provides superb tooling properties when applied by injection gun or spatula. 3M™ Aerospace Sealant AC-360 Class B has no added solvents, which gives you more sealant by purchase volume and reduces the need for rework due to shrinkage. Available in two work lives, with rapid cure times, AC-360 increases your workflow flexibility.
When used together, our Class A and B variants are ideal for sealing and/or repairing integral fuel tanks and sealing fuselages.
