SEALANT: FUEL TANK,A/B,BMS5-45CLB-1/2,QT, SEMKIT

PR-1750 Class B is an aircraft integral fuel tank 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-1750 Class B is a two-part, manganese dioxide cured polysulfide compound.
