PS870 Corrosion Inhibitive Sealant

PS870 is a corrosion inhibitive sealant.  It has a service temperature range from -54°C (-65°F) to 121°C (250°F), with intermittent excursions up to 135°C (275°F). This material acts as an effective barrier against the common causes of corrosion on aluminium alloys or between dissimilar metals. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas.

PS870 is a two-part, manganese dioxide cured polysulfide compound.  It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.

Class A is suitable for application by brush in thickness up to 25 mils.
Class B is a low sag, thixotropic paste suitable for application by extrusion gun or spatula.
Class C is designed for roller and faying surface sealing applications.

All variations are supplied in 100ml Semkits.
