  • Applications

    Benzenesulfonic acid, hydroxy-, aluminum salt (3:1) may serve as a processing aid and functional component in a range of industrial formulations due to its water solubility and ability to act as a counterion; in textiles it can function as a dye mordant/fixative for dyeing and printing processes; in coatings, paints and inks it can act as a stabilizer, dispersant and binding component to improve pigment dispersion and formulation stability; in polymers and plastics it can serve as a stabilizer or Lewis-acid catalyst for polymerization or resin curing, helping to control processing and film properties; in cleaning formulations and surface care products it can act as a chelating agent to bind metal ions and enhance cleaning efficiency; and in industrial manufacturing it can be used as a catalyst or processing aid for condensation or polymerization reactions.
