Abstract: Methods of curtain coating substrates are disclosed. In some embodiments, the methods include applying two or more liquid layers simultaneously to a substrate, wherein the multiple layers include a bottom liquid layer comprising a shear thinning liquid, and another liquid layer comprising a viscoelastic liquid. In some embodiments, the disclosed methods include formulating a bottom layer liquid comprising a shear thinning liquid, formulating another layer liquid comprising a viscoelastic liquid, pumping the bottom layer liquid and the other layer liquid through coating dies simultaneously and onto a moving substrate such that the bottom layer liquid impinges on the substrate thereby forming a bottom layer, and the other layer liquid forms another liquid layer above the bottom liquid layer. The inclusion of a bottom liquid layer comprising a shear thinning liquid and other layer comprising a viscoelastic liquid provides for enlargement of the curtain coating window.
