Abstract

Se describen métodos para el recubrimiento por cortina de sustratos. En algunas modalidades, los métodos incluyen aplicar dos o más capas líquidas simultáneamente a un sustrato, en donde las múltiples capas incluyen una capa líquida inferior que comprende un líquido pseudoplástico y otra capa líquida que comprende un líquido viscoelástico. En algunas modalidades, los métodos descritos incluyen la formulación de un líquido de capa inferior que comprende un líquido pseudoplástico, la formulación de otro líquido de capa que comprende un líquido viscoelástico, el bombeo del líquido de la capa inferior y el líquido de la otra capa a través de matrices de recubrimiento simultáneamente sobre un sustrato móvil de modo que el líquido de la capa inferior impacte contra el sustrato y forme así una capa inferior, y la otra capa líquida forme otra capa líquida sobre la capa líquida inferior. La inclusión de una capa líquida inferior que comprende un líquido pseudoplástico y otra capa que comprende un líquido viscoelástico proporciona la ampliación de la ventana de recubrimiento por cortina.
