PR 1750 Class S Sprayable Fuel Tank Sealant

A sprayable sealant designed for sealing integral fuel tanks and pressurised cabins. It has a service temperature range of -55°C (-67°F) to 180°C (356°F). The cured sealant has outstanding resistance to jet fuel, aviation gas and petroleum base lubricating oils.

PR-1750 Class S is a two-part manganese dioxide cured polysulfide liquid polymer. The mixed compound is of fluid consistency, suitable for application via spray. Once applied around fasteners, the material will not drip or flow from vertical or overhead surfaces. The sealant cures at room temperature and has excellent adhesion to aluminium, stainless steel, titanium and other common aircraft substrates.
