Abstract

Procedimiento de aglutinación a base de poliuretano para mezclas de materiales de moldeo, mezclas las que se destinan a la fabricación de moldes y machos de fundición con un poliisocianato que comporta dos grupos NCO, al menos por molécula, y con un poliol que incluye dos grupos OH, al menos, por molécula, preferentemente una resina sintética que comporta grupos OH, los cual forman los cuerpos partícipes en la reacción, con una amina terciaria o eventuralmente un compuesto organometálico que actúa como acelerador; así como un disolvente que está constituído por ésteres o que contiene ésteres, caracterizado por que, en los citados ésteres, el componente ácido es un ácido dicarboxílico alifático que incluye de 6 a 12 átomos de carbono, o bien un ácido benzol-policarboxílico que comporta 3 grupos COOH o más, mientras que el componente alcohol es un alcohol alifático, cicloalifático, arilalifático o aromático que comporta de 6 a 13 átomos de carbono.
