P/S 870 Class C is a corrosion inhibitive sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent up to 250°F (121°C), with intermittent excursions up to 275°F (135°C).
PS 870 Class C is a two-part, manganese dioxide cured polysulfide compound. The uncured material is designed for roller and faying surface sealing applications. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas.
