External Ammunition Sealant 76041
Hernon External Ammunition Sealant 76041 is a single component U.V. anaerobic sealant. 76041 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 and endures exposure to most solvents.
External Ammunition Sealant 76041 is a low 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 100 milliwatts/cm² to insure proper cure.
