External Ammunition Sealant 76081 is a single-component UV anaerobic sealant for bonding and sealing primers and case mouths in ammunition, designed for applications requiring high bullet pull forces and tight fit tolerances. It cures at room temperature without activators or heat, achieving fixturing strength in two to three minutes and full strength in 24 hours. The sealant has a viscosity of 8-15 cP at 25°C, a specific gravity of 1.0498, and a surface tension of 32.80 mN/m. It is UV-fluorescent for in-process inspection, cures under UV irradiances above 100 mW/cm², and operates reliably between -65°F and 250°F. The cured adhesive is a thermoset plastic resistant to most solvents and is a 100% solid system with no solvents. It is not recommended for use with plastics, oxygen-rich environments, or strong oxidizers. Dispensing equipment is available for high-speed automated application.
External Ammunition Sealant 76081 is a single component U.V. anaerobic sealant. 76081 has a low viscosity penetrating material capable of bonding and sealing primers and case mouths in ammunition. This Sealant is specially formulated for Ammunition that needs greater fit tolerance and higher bullet pull forces. Curing occurs when the adhesive is applied between mating surfaces. The cured adhesive is a thermoset plastic and endures exposure to most solvents. Ammunition Sealant 76081 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 three minutes. Full strength will be reached in 24 hours. Cure fillets at UV light irradiances above 100 milliwatts/cm² to insure proper cure.
