PPG AEROSPACE® Corrosion Inhibitive Sealants include different products offered in different classes and packings.
PPG AEROSPACE® P/S (Pro Seal) 870 Corrosion Inhibitive Sealants have a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275° (135°C). They act 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.
PPG P/S 870 Sealants are two-part, manganese dioxide cured polysulfide compounds.
P/S 870 Class A uncured material is suitable for application by brush in thickness up to 25 mils. It cures at room temperatures to form a resilient sealant having excellent adhesion to common aircraft substrates. Supplied in two-part kits and Semco® cartridges.
P/S 870 Class B 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. Available in two-part kits or Semkit® cartridges.
P/S 870 Class C uncured material is designed for roller and faying surface sealing applications. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates. Available in two-part kits and Semco® cartridges.

PPG PROSEAL P/S 890 Class A Fuel Tank Sealant
PPG PROSEAL P/S 890 Class A Fuel Tank Sealant
PPG AEROSPACE® Proseal P/S 890 Class A and B are aircraft integral fuel tank sealants. They have a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). Proseal P/S 890 Class A is designed for brush and fay sealing of fuel tanks and other aircraft fuselge sealing applications. Proseal P/S 890 Class B is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. The cured sealants maintain excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. Both are two-part, manganese dioxide cured polysulfide compounds. In the case of Proseal P/S 890 Class A, the uncured material is suitable for applicaiton by brush in thickness up to 25 mils. In the case of Proseal P/S 890 Class B, the uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula.Both cure at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates. PPG AEROSPACE® Proseal P/S 890 Class A and B sealants are supplied in two-part kits and Semco® cartridges.
