PR 1776 Class B-2 Fuel Tank Sealant Pint

A filleting compound low gravity for sealing integral fuel tank and pressurized cabins. PR 1776 class B was especially developed for use over a temperature range of -55°C to + 95°C and up to 160°C , with outstanding resistance to aircraft fuels (aviation gasoline or jet fuel) and petroleum base lubrificating oils.


PR 1776 class B is a two-part, high temperature resistant low gravity, fuel tank and fuselage sealant, based on Permapol P-5 liquid polymers, a chemically modified improved class of polysulfide polymers.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.
