Abstract

L'invention concerne l'obtention des moules de sable en fonderie. La composition contient une base de silice (sable), un silicate alcalin ou alcalino-terreux et, comme durcisseur, du mono-acétate de propylène-glycol. Cet ester confère aux noyaux de fonderie une plus grande résistance à la compression, qui se développe plus rapidement qu'avec les esters durcisseurs classiques. On pense que cela est dû, au moins en partie, à la pureté de l'ester et à sa miscibilité totale avec l'eau. Application : production de noyaux de sable pour la fonderie de métaux.
