Royal Adhesives & Sealants’ H­ardman WS 8020 RC rapid-cure manganese dioxide cured polysulfide aircraft sealant is qualified to SAE’s AMS 8802 Class B aircraft fuel tank sealant specification. The qualification enables faster aircraft assembly and reduced time for repair and maintenance. The sealant has good resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products. It also offers high flexibility and bond strength to most metal substrates. It has a work life of two hours but cures to 30 shore A in just 12 hours.­
