Abstract

La presente invencion suministra una composicion acuosa para su uso en la impermeabilizacion del cuero, la cual contiene una dispersion acuosa de un aceite de silicona emulsionada con un copolímero anfifílico, insoluble en agua, formado del 50 por ciento en peso al 90 por ciento en peos de al menos un monomero hidrofobico etilénicamente insaturado, y del 10 por ciento en peso al 50 por ciento en peso de al menos un comonomero hidrofílico, ácido o básico, etilénicamente insaturado, soluble en agua, copolimerizable; donde el copolímero tiene un peso molecular promedio ponderal de 2000 a 100,000; y donde la relacion del aceite de silicona al copolímero anfifílico, en peso, es de 1:5 hasta 8:1. También se suministra un método para impermeabilizar cuero, con el uso de dicha composicion acuosa.
