Abstract

Un aglutinante químico comprendiendo, un poliol basado en éster; un isocianato; y un catalizador capaz de catalizar una reaccion entre el poliol basado en éster y el isocianato. Preferiblemente, el aglutinante químico se usa en una mezcla moldeable comprendiendo un agregado en partículas y el químico. Dicha mezcla moldeable podría estar en, por ejemplo, un molde o matriz de fundicion desechable. También se produce para producir un molde de postura libre y un proceso para colar un metal.
