Abstract:
1. A process for manufacturing an ammunition article, comprising: (a) providing a cartridge including a projectile disposed in a casing and presenting a joint between the projectile and the casing; (b) applying to the joint a sealingly effective amount of a light-curable sealant composition, wherein the light-curable sealant composition (i) is not capillarily active at the joint, (ii) has a viscosity in a range from about 75 to 1000 centipoise at 25° C., and (iii) is UV-curable in exposure to ultraviolet radiation, curingly effective light therefor, within a time period of from about 0.01 to about 0.5 second, wherein a force of between 45 and 200 pounds is required to be applied to separate said projectile from said casing after cure of the light-curable sealant composition, and wherein the light-curable sealant composition is not anaerobically curing; and (c) exposing the applied sealant composition to curingly effective light comprising said UV radiation for a time period of from about 0.01 to about 0.5 second.
