Product Description Hernon Blank Ammunition Sealant 48641 Is a medium viscosity, UV and LED curable compound formulated to provide high performance, fast curing, coating and sealing of ammunition blank tips. This product is also used for shallow potting applications. Product Benefits • UV fluorescence for in-process inspection • LED curable • NO Solvents 100% solid system • Excellent adhesion to a variety of surfaces • Excellent environmental resistance • Good gap filling properties • No shrinkage due to solvent evaporation • Rapid room temperature cure Typical Properties (Uncured) Property Value Chemical Type Modified Acrylic Ester Appearance Purple, fluorescent liquid Viscosity @ 25oC, cP 600 to 800 Specific Gravity @ 25oC 1.01 Flash Point See MSDS Factors Affecting UV Curing • All UV sources degrade with use. Check output with a radiometer. • Thicker films require longer cures. • Light intensity decreases as distance from UV source increases. • Some clear plastics may contain UV inhibitors Precautions When Using UV Lamps • Never look directly at UV source. • Wear protective UV goggles • Use in a well-ventilated area. Some UV sources generate ozone. Provide shielding around high intensity UV sources. • High intensity UV sources generate heat. Take appropriate precautions. Typical Curing Performance Blank Ammunition Sealant 48641 will cure rapidly at room temperature when exposed to high intensity ultraviolet light (365 nm). UV light intensities above 100 mW/cm² will insure optimum surface cure.
