  • Applications

    1,1-Dichloroethane (CAS 75-34-3) is used as a solvent and chemical intermediate in industrial manufacturing. It serves as a feedstock for vinylidene chloride monomer, which is polymerized to PVDC barrier resins used in flexible packaging. It functions as a solvent in coatings, paints, inks, and adhesives, aiding resin dissolution and formulation. It is also employed as an industrial cleaning/degreasing solvent for metal surfaces and equipment. Additionally, it acts as a precursor for the synthesis of other chlorinated organic compounds, subject to local regulations and formulation limits.
