PR 1770 Class B High Strength Fuel Tank Sealant

A filleting compound for sealing integral fuel tank and pressurized cabins. PR 1770 class B 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.

PR 1770 class B is a two-part polysulfide Permapol P-5 liquid polymer. The mixed compound is a thixotropic paste, readily applied
by extrusion or injection gun, which does not flow from vertical or overhead surfaces. Sealant has excellent adhesion to aluminium, titanium, stainless steel, and other metals.
