  • Applications

    Potassium 2-(1'-ethoxy)ethoxypropionate (CAS 100743-68-8) can function as a surface-active agent and dispersant in cleaning, coatings, and ink formulations, supporting oil/water compatibility and pigment dispersion in industrial formulations. It is also used as an intermediate for the synthesis of glycol ether esters and related derivatives, serving as a building block in specialty chemical production. Additionally, it may act as a co-solvent or processing aid in coatings and cleaning formulations, improving wetting and blendability. In certain polymer systems, it can serve as a plasticizer or processing aid to adjust processability and mechanical properties of the final product.
