Abstract

La presente invención se refiere a una composición aglutinante endurecible para fundición, capaz de endurecerse por reacción con un ester orgánico, caracterizada porque comprende una solución acuosa de una resina resol formaldehído-fenol alcalino, que tiene una proporción molar de formaldehído: fenol en el rango de 1.2:1 a 2.6:1 y una proporción molar de álcali: fenol en el rango 0.2:1 a 1.2:1, la solución acuosa de la resina resol tiene un contenido de sólidos desde 25 a 75 por ciento en peso y una viscosidad en el rango de 20 a 1000 cP a 25 grados C, la cual composición además comprende un material carbonificable capaz de desprender 20 por ciento de su peso original de carbón lustroso cuando se mide por la prueba Bindernagel.The present invention relates to a curable foundry binder composition capable of curing by reaction with an organic ester, characterized in that it comprises an aqueous solution of a formaldehyde-alkaline phenol resole resin, which has a molar ratio of formaldehyde: phenol in the range 1.2: 1 to 2.6: 1 and an alkali: phenol mole ratio in the range 0.2: 1 to 1.2: 1, the aqueous solution of the resol resin has a solids content of 25 to 75 percent by weight and a viscosity in the range of 20 to 1000 cP at 25 degrees C, which composition further comprises a carbonifiable material capable of releasing 20 percent of its original weight of glossy carbon when measured by the Bindernagel test.
