Abstract

La presente se refiere a sistemas aglutinantes para fundición, que forman un poliuretano curable con una cantidad cataliticamente eficaz de un catalizador de curado, que comprende al menos un componente de resma fenólica que comprende al menos: una resina fenólica y un solvente de tipo triacetina para la resina fenólica y un componente de poliisocianato. La presente también se refiere a mezclas para fundición preparadas a partir del aglutinante y un árido, a formas para fundición tales como machos y moldes preparados a través de procesos sin horneado o de caja fría, y también a los procedimientos respectivos. Las formas para fundición obtenidas a través de la presente se utilizan especialmente para la fabricación de componentes metálicos, en especial, para moldear componentes metálicos.
