1. A system for applying a first coating composition, a second coating composition, and a third 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 third 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 first reservoir in fluid communication with the first high transfer efficiency applicator and configured to contain the first coating composition;
a second reservoir in fluid communication with the second high transfer efficiency applicator and configured to contain the second coating composition;
a third reservoir in fluid communication with the third high transfer efficiency applicator and configured to contain the third coating composition; and
a substrate defining a target area;
wherein the first high transfer efficiency applicator is configured to receive the first coating composition from the first reservoir and configured to apply the first coating composition through the array of nozzles of the first high transfer efficiency applicator to the target area of the substrate at a thickness of from about 5 to about 50 microns;
wherein the second high transfer efficiency applicator is configured to receive the second coating composition from the second reservoir and configured to apply the second coating composition through the array of nozzles of the second high transfer efficiency applicator to the target area of the substrate at a thickness of from about 5 to about 50 microns;
wherein the third high transfer efficiency applicator is configured to receive the third coating composition from the third reservoir and configured to apply the third coating composition through the array of nozzles of the third high transfer efficiency applicator to the target area of the substrate at a thickness of from about 5 to about 50 microns;
wherein each of the first, second, and third coating compositions independently has a solids content of from about 5 to about 70 weight % based on a total weight of the first 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 first coating composition, and a crosslinker present in an amount of from about 1 to about 20 weight percent based on a total weight of the respective coating composition, and wherein each of the first, second, and third coating compositions independently 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;
an Ohnesorge number (Oh) of from about 0.01 to about 12.6;
a Reynolds number (Re) of from about 0.02 to about 6,200; and
a Deborah number (De) of from greater than 0 to about 1730.
