Abstract
La presente invención se refiere a mezclas de fundición que comprenden un agregado seco de fundición y un aglutinante de fundición formador de poliuretano. Los componentes del aglutinante incluyen un componente de polieterpoliol y un componente orgánico de poliisocianato que se cura con un catalizador de amina líquida terciaria. Las mezclas de fundición se utilizan para preparar figuras de fundición hechas de mezclas de fundición mediante un proceso que no requiere horneado. Las figuras de fundición que resultan se utilizan para vaciar partes metálicas de metales ferrosos y no ferrosos.
