PR 1770 Class C High Strength Fuel Tank Sealant

A filleting compound for sealing integral fuel tank and pressurized cabins. PR 1770 class C was especially developed for use over a temperature range of -55°C to 120°C up to 180°C and with outstanding resistance to aircraft fuels (aviation gasoline or jet fuel) and petroleum base lubrificating oils.

The mixed compound is a trowlable liquid that may be applied with a  brush, trowel or roller and does not flow from vertical or overhead surfaces after application as a faying surfaces sealant.
