N2 - Nitrocellulose and polyurethane were coated on Cu-Sn composite frangible projectile in different coating methods. In this research, dip coating and spray coating methods were applied to frangible projectiles. According to the experiment's result, dip coating product of nitrocellulose and polyurethane have a similar thickness (9,1μm). Additionally, the thickness of the spray coating product is 2 μm, smaller than dip coating. The large number of thickness increase mass gain percentage of dip-coating product and affect its drag force. Drag force calculation and ballistic test show a good agreement between coated and uncoated projectile. The calculated drag force values confirmed of 39.028-39.104 N, and ballistic test of 39.125-39.314 N for coated composite. The values it slightly higher compared than without coating (38.997 N) but considered acceptable.
