Abstract
METODO PARA PREPARAR UNA COMPOSICION DE CUERO IMPREGNADO. SE IMPREGNA UNA HOJA DE CUERO CON UNA DISPERSION IONICA ACUOSA DE UN POLIMERO DE POLIURETANO QUE TIENE GRUPOS IONIZABLES SOLUBILIZADORES, UNIDOS DE MANERA COVALENTE A LA CADENA POLIMERA. SE COAGULA DE MANERA IONICA DICHO POLIMERO DE POLIURETANO A PARTIR DE LA DISPERSION QUE IMPREGNA A DICHO CUERO DE BAJO PESO ESPECIFICO. SE CALIENTA EL CUERO IMPREGNADO, BAJO CALOR Y PRESION, SIENDO APLICADOS DICHOS CALOR Y PRESION A POR LO MENOS UNA SUPERFICIE DEL MISMO PARA DESARROLLAR UNA CAPA DE GRANO.
