Description
P/S 872 Class B is a conductive lightning strike and corrosion inhibitive sealant from PPG Aerospace. It is a two-part, aluminium-filled, manganese dioxide cured polysulfide that mixes to a low-sag paste and cures at room temperature. PPG rates it from -54°C to 121°C, with intermittent excursions to 135°C.
The manufacturer describes it for maintaining electrical continuity in highly torqued fay surfaces in certain aircraft applications, while acting as a corrosion barrier on aluminium alloys and between dissimilar metals. It tolerates intermittent jet fuel and aviation gas exposure.
