Fuel Tank Sealant

Fuel Master FAC 240 Class B is a two-part, polysulfide-based product for use as a long application life, quick cure sealant for integral fuel tanks and fuselages. The mixed compound has a thixotropic, non-sag consistency and can be readily applied with a spatula or extrusion gun on vertical surfaces. It will cure to a fuel-resistant rubber at temperatures above 30°F and exhibits excellent tooling properties with very low shrinkage.
