Abstract

Pour préparer des noyaux et des moules de fonderie sans cuisson pour le moulage par coulée des métaux, on utilise un liant constitué d'un polyol, obtenu de façon générale par alcoxylation d'une amine, et un polyisocyanate ; le liant est particulièrement utile pour la coulée des métaux non ferreux par exemple de l'aluminium, du magnésium et autres; les noyaux et les moules pour la coulée de l'aluminium et des autres métaux légers présentent d'excellentes caractéristiques d'élimination par secousses et d'autres propriétés souhaitables; on a également constaté que les liants de l'invention ont une nature autocatalytique. L'invention s'applique en particulier à la formation de pièces coulées en métaux légers avec des articles de fonderie qu'il est facile de séparer des pièces coulées.
