Abstract

"PROCESSO PARA MELHORAR A RESISTêNCIA à UMIDADE DE AGLUTINANTES DE FUNDIçãO DE URETANO FENóLICO". Uma modalidade da presente invenção apresenta um processo para melhorar a resistência à tração de núcleos e moldes de fundição. Mais particularmente, uma modalidade da presente invenção apresenta um aglutinante aperfeiçoado para núcleos e moldes de fundição, que inclui um ácido portador de fluoreto em combinação com um composto de silício inorgânico. Alternativamente, o aglutinante aperfeiçoado pode incluir um ácido portador de fluoreto em combinação com um composto de boro. Em uma modalidade preferida, um componente aglutinante parte 1 modificado inclui uma combinação de ácido fluorídrico e um composto de silício inorgânico.
