Methylene Chloride

METHYLENE CHLORIDE 270KG – NON-FLAMMABLE, FAST-EVAPORATING EXTRACTION SOLVENT

Methylene Chloride (Dichloromethane) is a colourless, non-flammable organic solvent that evaporates quickly and offers strong extraction power. It is used in paint stripping, extraction, industrial cleaning and many applications.

PRODUCT INFORMATION / Introduced packaging: 270 kg/drum. The product is a non-flammable, fast-evaporating liquid; vapours are heavier than air. Acceptance criteria must be based on the COA of the actual batch delivered.

1. What Is METHYLENE CHLORIDE 270KG?

Methylene Chloride (MC) is an organic compound with the formula CH2Cl2, a colourless, fast-evaporating liquid with a mild sweet odour. Thanks to its strong solvency and extraction power and its non-flammable nature under normal conditions, MC is used as a paint-stripping solvent, extraction solvent, industrial cleaning agent and in pharmaceutical production. Vapours are heavier than air, so good ventilation is required.

5. Instructions for Use

• Use according to the technical guidance and recommended parameters of the manufacturer.
• Blend only with materials whose compatibility has been assessed.
• Perform compatibility and small-scale tests before full-scale production.
• Check shelf life, container condition and labels before use.
• Do not mix with incompatible chemicals without a technical assessment.

6. Safety, Storage and Transportation

• Wear safety goggles, gloves, organic-vapour respirator and protective clothing when handling Methylene Chloride.
• Work in a well-ventilated area; vapours are heavier than air and may accumulate in low-lying areas.
• Store in a dry, cool warehouse away from heat sources; keep drums on pallets.
• Keep containers closed when not in use; keep away from open flame, sparks, static electricity and heat sources.
• Separate from strong oxidisers and incompatible chemicals.
• Do not discharge large quantities into drains, surface water or groundwater.
• Protect cargo from rain, secure the load and keep labels intact.
• If large amounts of vapour are inhaled, move the person to fresh air and seek medical attention. In case of eye contact, rinse with clean water for at least 15 minutes.

7. Selection and Acceptance Criteria

• Verify the COA of the actual delivered batch against the technical requirements.
• Check appearance, colour, clarity and visible impurities.
• Check container condition, seals, labels and traceability information.
• Review the SDS for storage and emergency handling.
• Check homogeneity, water-insoluble matter and batch-specific parameters.
