Factory Wholesale Industry Grade Dichloromethane DCM 99% Min Colorless Transparent Liquid CAS 75-09-2 For Paint Remover Precision Metal Cleaning Pharm

Dichloromethane (DCM), also universally known as Methylene Chloride, is a highly versatile, fast-volatile, non-flammable chlorinated organic solvent with the chemical formula CH₂Cl₂ and CAS number 75-09-2. Our factory-supplied Industrial Grade 99% Dichloromethane is produced through advanced methanol hydrochlorination synthesis, high-precision continuous rectification, deacidification purification, moisture removal and stabilized formula blending processes, strictly eliminating residual chloroform, carbon tetrachloride, acidic substances, water content and heavy volatile impurities to ensure stable 99.0% minimum purity and ultra-stable industrial performance for large-scale wholesale applications.

Under standard room temperature and pressure conditions, Dichloromethane appears as a completely colorless, transparent and clear low-viscosity liquid with a mild, sweet ethereal odor. It features a low boiling point of approximately 39.8°C, enabling extremely fast evaporation with zero residual film, zero water marks and zero surface contamination after cleaning workpiece surfaces. Different from flammable hydrocarbon solvents, alcohol solvents and ester solvents, DCM is completely non-flammable and non-explosive under normal industrial operating environments, providing superior safety for closed vapor degreasing machines, heating cleaning lines and industrial solvent formulation workshops. Its vapor density is significantly higher than air, allowing easy containment in sealed equipment, effectively reducing solvent volatilization loss and improving overall production cost efficiency.

This industrial grade DCM is formulated with a professional anti-decomposition stabilizer system, which effectively inhibits photolysis, hydrolysis and acidification reactions during long-term storage, high-temperature circulation and repeated distillation recovery. It prevents hydrochloric acid generation, avoids equipment corrosion, metal workpiece oxidation and surface tarnishing, and greatly extends the service life of solvent liquid in industrial circulating cleaning systems. The product exhibits excellent universal solubility and strong dissolving power toward a wide range of industrial contaminants, including mechanical lubricating grease, cutting oil, stamping oil, anti-rust wax, polishing paste, aged paint coatings, acrylic resin, epoxy residue, polyurethane adhesive, printing ink, rubber residue and organic dirt. It can rapidly strip thick paint layers and dissolve stubborn organic deposits without causing corrosion or damage to stainless steel, aluminum alloy, copper, iron and most rigid plastic materials.

Benefiting from its unique physical and chemical properties, 99% Dichloromethane has become one of the most widely used bulk industrial solvents in global manufacturing industries. In precision metal processing, it serves as the core medium for closed vapor degreasing, achieving ultra-high cleanliness surface treatment for automotive parts, mechanical bearings, electronic hardware terminals, optical components and precision stamping parts. In coating and paint stripping industries, it is the primary raw material for high-efficiency industrial paint removers, thoroughly removing old baking paint, anti-corrosion coatings and surface paint layers on molds, mechanical equipment and metal structural parts.

In pharmaceutical and fine chemical industries, DCM acts as a low-temperature extraction solvent and reaction medium for natural plant extracts, antibiotic intermediates, vitamin formulations and biochemical raw materials. Its low boiling point allows fast and low-temperature solvent recovery, effectively protecting heat-sensitive active ingredients from thermal decomposition and ensuring high extraction purity and yield. In polyurethane manufacturing, it functions as a physical foaming agent for rigid PU thermal insulation foam boards, refrigeration equipment foam layers and building insulation materials, providing uniform foam pore structure and stable thermal insulation performance.

Furthermore, Dichloromethane is extensively applied in printing and packaging industries for ink cleaning and roller residue removal, in adhesive industries for glue dilution and residual adhesive cleaning, and in leather processing for efficient degreasing treatment. It is also commonly used as an auxiliary solvent for aerosol cleaning agents, industrial detergent formulations and chemical synthesis intermediates.

All batches of our 99% industrial grade Dichloromethane undergo strict full-item laboratory testing, including GC gas chromatography purity analysis, water content detection, acidity test, residue content test and color comparison inspection. Every batch is guaranteed low impurity, low acidity, low moisture and stable physical indicators. The finished product is sealed and packaged in nitrogen-filled galvanized iron drums and IBC tanks to isolate light, moisture and air oxidation during long-distance maritime transportation and long-term warehouse storage. We support bulk wholesale full-container orders, long-term stable supply contracts and small-batch trial orders, and can provide complete COA batch analysis certificates, MSDS safety data sheets and third-party qualification reports to meet global industrial customer procurement and customs clearance standards.
