Abstract

esta invenção refere-se a composições e métodos para redução de odor e emissão de formaldeído durante a produção e cura de núcleos e moldes, particularmente aqueles núcleos e moldes da indústria de fundição que compreendem aglutinantes fenólicos curáveis por éster. mais especificamente, aqui incluído é um éster-curativo compreendendo um éster e resorcinol que, quando fornecido numa composição com uma resina e um agregado, elimina eficazmente o formaldeído que não reagiu, reduzindo assim a emissão e o odor dos mesmos a partir da composição.
