Overview
P/S Class B is an conductive lightning strike, corrosion inhibitive sealant. It has a service temperature range from -67 to 250 deg F, with intermittent excursions up to 275 deg F. The cured sealant maintains electrical continuity in a highly torqued fay surfaces for certain aircraft applications. This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. The cured material is resistant to intermittent exposure to both jet fuel and aviation gas. P/S 872 class B is a two-part aluminum filled manganese dioxide cured, polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
