  • Applications

    2-Ethoxybutane (CAS 2679-87-0) is an ether with solvent-like properties used as a nonpolar to moderately polar solvent and as an intermediate in chemical manufacturing. In coatings and inks, it serves as a solvent to dissolve resins and pigments; in adhesives, it functions as a solvent component to improve resin solubility and processing; in polymer and plastics processing, it is used as a processing solvent and as an intermediate for surface-treatment reactions; in cleaning formulations, it can be used as an industrial solvent to dissolve oils and residues.
