121 Tech Drive Sanford, FL 32771 (407) 322-4000 Fax: (407) 321-9700 www.hernon.com Technical Data Sheet External Ammunition Sealant 59521 High Performance Adhesives and Sealants Product Description Typical Cured Performance Hernon External Ammunition Sealant 59521 is a single component U.V. 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. Ammunition Sealant 59521 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 60 milliwatts/cm² to insure proper cure. Product Benefits • 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 • Excellent capillary performance Typical Properties (Uncured) Property Blue liquid Specific Gravity Flash Point Anaerobic fixture time, brass UV tack free time, s Handling Time at 23ºC, mins. General Information This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials. For safe handling information on this product, consult the Material Safety Data Sheet (MSDS). Where aqueous washing systems are used to clean the surfaces before bonding, it is important to check for compatibility of the washing solution with the adhesive. In some cases these aqueous washes can affect the cure and performance of the adhesive. This product is not normally recommended for use on plastics (particularly thermoplastic materials where stress cracking of the plastic could result). It is recommended to confirm compatibility of the product with such substrates. Directions For Use Shake well before use. Ammunition Sealant 59521 should be applied in sufficient quantity to fill the rim around Primer cavities. Application of Adhesive for Bullet Sealing 1. Ammunition Sealant 59521 is dispensed to the edge of the case where it penetrates around the joint in less than 5 seconds. Hernon dispensing equipment employs a valve fitted with a hypodermic needle that actually touches the joint; the air actuated valve controls the adhesive quantity dispensed. 2. Bullets can then be cured with a high intensity UV lamp (2 to 4 second cure at 365 nm). 3. UV protective glasses and gloves should be worn for protection against the UV light. 4. A low-powered UV lamp can be used to inspect for the presence of adhesive.
