Abstract

"SISTEMA AGLUTINANTE, MISTURA DE FUNDIçãO PROCESSO PARA PREPARAR UMA FORMA DE FUNDIçãO, E, PROCESSO PARA MOLDAR UM METAL". A presente invenção está relacionada a um sistema aglutinante que compreende um componente de resina fenólica e um componente de poliisocianato. Esse sistema é caracterizado pelo fato de que o componente de resina fenólica inclui uma resina fenólica alcoxi-modificada onde menos de 25% em moles dos grupos hidroxila fenólicos são eterificados com um álcool alifático primário ou secundário compreendendo entre 1 e 10 átomos de carbono.
