Abstract

La dispersion acuosa de una o más resinas de poliuretano con un numero de peso molecular promedio de (Mn) de 2500 a 100 000, un contenido de 2 a 150 mmol de enlaces de siloxano (-Si-O-Si-) por 100 g de resina solida, un valor hidroxilo de 0 a 100 y un contenido de grupos ionicos, grupos que se convierten en grupos ionicos y/o grupos hidrofílicos de 5 a 200 mEq por 100 g de resina solida y el procedimiento para la produccion de las mismas mediante extension de cadena de un prepolímero de poliuretano que contiene grupos ionicos, grupos capaces de formar iones y/o grupos hidrofílicos los cuales tienen por lo menos un grupo R'OSi- en el cual R' = C1 a C8 alkyl o C(O)R''' y R''' = C1 a C10 alkyl mediante la adicion de agua. La dispersion acuosa es apropiada para composiciones de revestimiento acuosas que son apropiadas en particular para revestimientos de laca de capas multiples.
