Hernon® External Ammunition Sealant 59521 (Blue)
Hernon External Ammunition Sealant 59521 is a single component UV anaerobic sealant. 59521 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. Hernon® Blank Ammunition Sealants are a complete line of UV Cure adhesives.
