3M™ Aerospace Sealant AC-350 is a family of intermediate density, fast-curing, polysulfide fuel tank sealants that provides outstanding resistance to aviation fuels and petroleum chemicals. The Class A, B and C 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.

The 3M™ Aerospace Sealant AC-350 family of polysulfide sealants provide a number of advantages and benefits compared to traditional sealants. With three classes, they meet a wide range of manufacturing and maintenance needs.

Class Distinction
When 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 in three different work lives, 3M™ Aerospace Sealant AC-350 Class A gives you the flexibility you need for various requirements. Rapid cure times keep your processes moving forward.

The Class B version mixes to a thixotropic paste that provides superb tooling properties when applied by injection gun or spatula. 3M™ Aerospace Sealant AC-350 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 multiple work lives, with rapid cure times, AC-350 increases your workflow flexibility.
