External Ammunition Sealant 76084 is a single component UV anaerobic sealant. 76084 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 suitable for temperatures up to 400ºF (204ºC) and endures exposure to most solvents.
Ammunition Sealant 76084 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 ensure proper cure.
• UV fluorescence for in-process inspection
• 100% solid system (no solvents)
• Excellent environmental resistance
• Good gap filling properties
• Excellent Bullet Pull strengths with low Standard deviation
• UV and anaerobic curing mechanism suitable for metal parts
• Good capillary performance
Disassembly and Cleanup
Non-cured sealant can be removed with Hernon Cleaner 62.
Ammunition Sealant 76084 should be stored in a cool, dry location away from light in unopened containers at a temperature between 46ºF to 82ºF (8ºC to 28ºC) unless otherwise labeled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused material, do not return any material to its original container.
