PPG PS870 B-2 Corrosion Inhibitive Sealant

This material acts as an effective barrier against the common causes of corrosion on aluminium alloys or between dissimilar metals. Thecured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas.

PS 870 Class B is a two-part, 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.

The following tests are in accordance with MILPRF-81733 Type II specification test methods.
