Abstract

La présente invention concerne un catalyseur fluide pour le durcissement de liants à base de résines. Ce catalyseur contient jusqu'à 5% en poids d'eau jusqu'à 10% en poids d'acide sulfurique, et le complément étant sensiblement un mélange d'acide benzène sulfonique et d'acide alkylbenzène sulfonique contenant jusqu'à 12 atomes de carbone, ledit mélange contenant de 20 à 80% en poids d'acide benzène sulfonique et de 20 à 80%, en poids d'acide alkylbenzène sulfonique ayant de 8 à 9 atomes de carbone. Application de ce catalyseur au durcissement de moules de fonderies.The present invention relates to a fluid catalyst for curing resin-based binders. This catalyst contains up to 5% by weight of water up to 10% by weight of sulfuric acid, and the remainder being substantially a mixture of benzene sulfonic acid and alkylbenzene sulfonic acid containing up to 12 carbon atoms. carbon, said mixture containing from 20 to 80% by weight of benzene sulfonic acid and from 20 to 80% by weight of alkylbenzene sulfonic acid having 8 to 9 carbon atoms. Application of this catalyst to the hardening of foundry molds.
