External Ammunition Sealant 76020
External Ammunition Sealant 76020 is a single component U.V. anaerobic sealant. 76020 has a low viscosity penetrating material capable of bonding and sealing primers and case mouths in ammunition. It is specially formulated for pre-assembled components; it works by capillary action sealing ammunition and improving bullet pull force. Curing occurs when the adhesive is applied between mating surfaces. The cured adhesive is a thermoset plastic suitable for temperatures up to 400ºF (204ºC) and endures exposure to most solvents.
External Ammunition Sealant 76020 is a medium-strength sealant that cures quickly at room temperature without the need for surface activators or heat to seal primer and case mouth assemblies. Fixturing strength develops in two to five minutes, Full strength will be reached in 24 hours. Cure fillets at UV light irradiances above 60 milliwatts/cm² to ensure proper cure.
