Product Description

Dichloromethane (DCM, CAS 75-09-2) is a volatile, polar aprotic solvent widely used in coatings, adhesives, extraction, degreasing and chemical synthesis. It offers excellent solvency for resins, waxes and many organic compounds, and is supplied in industrial and reagent grades for manufacturing and laboratory use.

Application

  • Coatings & adhesives
    Used as a solvent and viscosity reducer for coatings, lacquer and adhesive formulations.
  • Extraction & separations
    Employed in laboratory and industrial extraction processes for organic compounds and natural products.
  • Degreasing & metal cleaning
    Used in limited industrial cleaning and degreasing operations where rapid solvency and volatility are required.
  • Polymer processing & resin formulation
    Serves as a solvent for polymer dissolution, resin processing and formulation adjustments.
  • Analytical and laboratory reagent
    Provided as a reagent solvent for chromatography, sample preparation and method development.
