Overview
PR-1422 Class A Fuel Sealant PR-1422 Class A is an aircraft integral fuel tank sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. PR-1422 Class is a two-part, dichromate 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. - See more at: http://www.ppgaerospace.com/getdoc/572f7cad-14e1-4a0e-aee0-c994b9a6dece/PR-1422-Class-A-Fuel-Sealant.aspx#sthash.YpoGITZ0.dpuf
