P/S 875 Class B is a low weight corrosion inhibitive sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. It offers as much as a twenty percent weight savings, per unit volume, over traditional sealants used for these purposes The cured sealant maintains excellent elastomeric properties after limited exposure to both jet fuel and aviation gas.

P/S 875 Class B is a two part, chemically curing, Permapol® P-5 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.
