This two-part corrosion inhibitive sealant is designed for use on aluminum alloys and dissimilar metals. It cures at room temperature, forming a resilient seal with strong adhesion to aircraft substrates. The sealant maintains elastomeric properties when exposed to jet fuel and aviation gas, providing effective corrosion protection.This two-part corrosion inhibitive sealant is

Overview
P/S 870 Class B corrosion inhibitive sealant. This material acts as an effective barrier against the common causes of corrosion on the aluminum alloys or between dissimilar metals. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas. P/S 870 Class B 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.
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
