  • Applications

    Zinc phenolsulfonate is primarily used as an intermediate and functional salt in chemical synthesis, enabling zinc coordination in dye and pigment manufacture and serving as a precursor for sulfonated phenol derivatives. In industrial manufacturing, it is commonly employed as a chelating agent and processing additive to stabilize formulations, improve metal-ion control, and enhance washfastness in coatings and inks. It can act as a crosslinking or stabilizing component in certain polymer and adhesive systems, and may serve as a zinc source in specialty chemical formulations under applicable regulatory and formulation limits. Typical domains include coatings/inks, polymers/plastics, cleaning, and specialty formulations, as well as zinc-containing intermediates for dye and pigment production.
