Abstract
La presente se refiere a una composicion y método para mejorar la resistencia a la traccion de nucleos y moldes de fundicion sobre la que se podía obtenerde manera convencional. El uso de un compuesto acídico de metileno en las composiciones deaglom erantes que incluyen resinas resol fenolicas fuertementealcalinas da como resultado un aglomerante curable de éster que se puede emplear para fabricar nucleos y moldes de fundicion que tienen resistencias a latraccion mucho mayores que lasque se po dían obtener con los aglomerantes del arte previo. Dicha composicion util para la preparacion de moldes de fundicion,comprende: a) un compuesto acídico de metileno; y b) un compuesto elegido del grupo que comprende: - una resina resolfenolica que ti ene un pH de por lo menos10,5; o - un curador de éster; o - sus mezclas. También se describen los métodos para fabricar dichos moldes de fudicion utilizando dicha composicion.
