1. A method of applying a coating composition to a substrate utilizing a high transfer efficiency applicator, wherein the coating composition has a solids content of from about 15 to about 70 weight % based on a total weight of the coating composition as measured in accordance with ASTM D2369 and comprises a carrier, a binder present in an amount of from 15 to about 70 weight percent based on a total weight of the coating composition, and a crosslinker present in an amount of from about 0.1 to about 25 weight percent based on a total weight of the coating composition, wherein the coating composition has a viscosity of from about 0.002 Pa*s to about 0.2 Pa*s as measured according to ASTM 7867-13 with cone-and-plate or parallel plates at a shear rate of 1000 sec-1, a density of from about 838 kg/m3 to about 1557 kg/m3, a surface tension of from about 0.015 N/m to about 0.05 N/m, and a relaxation time of from about 0.00001 to about 1 s, the method comprising the steps of:
providing the coating composition to the high transfer efficiency applicator comprising a nozzle, the nozzle defining a nozzle orifice having a nozzle diameter in an amount of from 0.00002 m to 0.0004 m; and
applying the coating composition to the substrate through the nozzle orifice to form a coating layer;
wherein at least 80% of the droplets of the coating composition expelled from the high transfer efficiency applicator contact the substrate.
