DeSoto® PS890A1-2PT Fuel Tank Sealant, 1 pt, Liquid, Black/Beige (Part A/B)

P/S 890 Class A is an aircraft integral fuel tank sealant. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. P/S 890 Class A is a two-part, manganese dioxide cured polysulfide compound. The uncured material is suitable for application by brush in thickness up to 25 mils. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
