Abstract

Se conoce el uso de ácidos alquilbencenosulfónicos como catalizadores para el fraguado de ligantes resinosos de los moldes de fundición. Esta invención proporciona mezclas constituidas por hasta 5% en peso de agua, hasta 10% en peso de ácido sulfúrico y el resto constituido esencialmente por una mezcla de ácidos bencenosulfónicos de hasta 12 átomos de carbono, conteniendo dicha mezcla de 20 a 80% en peso de ácido bencenosulfónico y de 20 a 80% en peso total de ácidos alquilbencenosulfónicos de 8 a 9 átomos de carbono. La nueva mezcla presenta una viscosidad sinérgicamente redudida.
