Abstract

La presente invención se refiere a un metodo para curar el aglutinante en un molde o macho de fundición, hecho con un material refractario granular, junto con un aglutinante basado en un poliacrilato alcalinometálico soluble en agua, que incluye un aditivo que, cuando menos en parte, incluye cal; el metodo consiste en pasar, a traves del molde o macho, un gas portador que contiene una proporción considerable del vapor de un ester alquílico que no contiene más de tres átomos de carbono, o una mezcla de dichos esteres.
