Royal Adhesives WS-8020RC B1/2 Fuel Tank & Fuselage Sealant (AMS-S-8802 B 1/2 / AMS3276 / CMNP021 )

WS-8020 Class B is two-component manganese dioxide cured polysulfide sealant designed for fuel tank and fuselage applications. The cured sealant has excellent fuel resistance as well as outstanding sealing characteristics at temperatures ranging from -65F (54C) to 250F (121C), including intermittent exposure up to 360F (182C).WS-8020 Class B exhibits excellent elastomeric properties and retention after prolonged exposure to jet fuel and aviation gasoline. The uncured product is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature forming a resilient rubber, exhibiting outstanding sealing characteristics.WS-8020 Class B conforms to the requirements of AMS-8802, AMS3276, and CMNP021 specifications.Formerly: MIL-S-8802
