P/S 870 Class C is a corrosion inhibitive sealant that acts as an effective barrier against common causes of corrosion on aluminum alloys and between dissimilar metals. It is a two-part, manganese dioxide cured polysulfide compound.
WARNING: This product can expose you to chemicals including CHROMIUM (HEXAVALENT COMPOUNDS), TITANIUM DIOXIDE (AIRBORNE, UNBOUND PARTICLES OF RESPIRABLE SIZE) and TOLUENE which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm.

Overview
The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas. The uncured material is designed for roller and faying surface sealing applications. It cures at room temperature to form a resilient sealant with excellent adhesion to common aircraft substrates. The service temperature range is from -65 °F (-54 °C) to 250 °F (121 °C), with intermittent excursions up to 275 °F (135 °C). The C-12 classification indicates an application life of 12 hours. The storage life of P/S 870 Class C is at least 6 months when stored at temperatures below 80 °F (27 °C) in original, unopened containers.
Features & Benefits
Low temperature flexibility at -65°F (-54°C) with no cracking, checking, or loss of adhesion
Resistance to hydrocarbons for enhanced durability
Flexibility with no cracks after bending 180 degrees over a 0.125 inch (3.18 mm) mandrel
Repairable to itself, excellent for both freshly cured and fuel-aged fillets
Fungus resistant and non-nutrient
Salt spray (fog) test for 670 hrs. (ASTM B117) shows no corrosion to base substrate or deterioration of sealant
