High transfer efficiency application process for low temperature curing coating compositions and coated substrates formed therefrom

A method and composition for forming a coating on a substrate, the method comprising: a) applying an aqueous coating composition to at least a portion of the substrate using a high transfer efficiency applicator that discharges the coating composition; and b) curing the coating composition to form a cured coating. The aqueous coating composition includes an aqueous carrier, a film-forming resin having at least one cross-linking functional group, and a co-reactive material having at least one functional group that is reactive with the cross-linking functional group. The cured coating of the aqueous coating composition reaches 100 MEK double twist after baking at 80 DEG C for 30 minutes at a coating thickness of 35 [mu] m, as measured according to ASTM D5402-19 (2019). 用于在基材上形成涂层的方法和组合物，所述方法包含：a)使用排出水性涂料组合物的高转移效率施涂器将所述涂料组合物施涂于所述基材的至少一部分；以及b)使所述涂料组合物固化以形成固化的涂层。所述水性涂料组合物包含水性载体、具有至少一个交联官能团的成膜树脂以及共反应材料，所述共反应材料具有与所述交联官能团具有反应性的至少一个官能团。所述水性涂料组合物的所述固化的涂层在35μm的涂层厚度下在80℃下烘烤30分钟后达到100MEK双搓，如根据ASTM D5402-19(2019)测量的。
