1. A system for applying a coating composition, the system comprising:
a first high transfer efficiency applicator comprising an array of nozzles wherein each nozzle defines a nozzle orifice having a diameter of from 0.00002 m to 0.0004 m;
a second high transfer efficiency applicator comprising an array of nozzles wherein each nozzle defines a nozzle orifice having a diameter of from 0.00002 m to 0.0004 m;
a reservoir in fluid communication with the first high transfer efficiency applicator and the second high transfer efficiency applicator configured to contain the coating composition; and
a substrate defining a first target area and a second target area;
wherein the first high transfer efficiency applicator is configured to receive the coating composition from the reservoir and configured to apply the coating composition to the first target area of the substrate through the nozzle orifice without atomization such that at least 99.9% of the applied coating composition contacts the first target area of the substrate;
wherein the second high transfer efficiency applicator is configured to receive the coating composition from the reservoir and configured to apply the coating composition to the second target area of the substrate through the nozzle orifice without atomization such that at least 99.9% of the applied coating composition contacts the second target area of the substrate,
wherein the coating composition has a solids content of from about 5 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 5 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;
wherein the coating composition has an Ohnesorge number (Oh) of from about 0.01 to about 12.6;
wherein the coating composition has a Reynolds number (Re) of from about 0.02 to about 6,200;
wherein the coating composition has a Deborah number (De) of from greater than 0 to about 1730;
wherein the coating composition has a density of from about 838 kg/m3 to about 1557 kg/m3;
wherein the coating composition has a surface tension of from about 0.015 N/m to about 0.05 N/m; and
wherein the coating composition has a relaxation time of from about 0.00001 to about 1 s.
