PPG Aerospace/PRC DeSoto® Corrosion Inhibitive Sealant Solid Black/White (Part A/B) 1qt PR1775B2-1QT

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.
