PPG Aerospace/PRC DeSoto® Desothane® Fuel Tank Sealant 6 Oz Liquid (Part A) Solid (Part B) Black PR2001B1-2

PR-2001 Class B is a rapid cure, low odor, aircraft integral fuel tank, fuselage and aerodynamic smoothing sealant. This material is designed for fillet sealing of 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-2001 Class B is a two-part, epoxy cured Permapol® P-3.1 polythioether compound. Unlike standard polysulfide fuel tank sealants, it can cure at low-temperatures and is unaffected by changes in relative humidity. This sealant has excellent adhesion to properly prepared common aircraft substrates.
