What is methylene dichloride?
Methylene dichloride (CH₂Cl₂)-also known as dichloromethane (DCM) or methylene chloride-is a highly effective blowing agent used in the production of polyurethane (PU) and other polymer foams. Due to its low boiling point (39.6°C), high volatility, and excellent solvent properties, it plays a crucial role in creating lightweight, insulating, and flexible foam materials.
Methylene Dichloride Formula
The chemical formula for methylene dichloride is CH₂Cl₂, indicating that each molecule consists of:
One carbon atom (C)
Two hydrogen atoms (H)
Two chlorine atoms (Cl)
This structure makes it an excellent solvent for resins, adhesives, and paint strippers.

Why Use Methylene Dichloride Paint Stripper on Metal?
Metal surfaces-ranging from automotive parts and machinery to antique furniture and architectural elements-require a paint stripper that is both aggressive and non-damaging. Methylene chloride-based strippers are ideal for this purpose because:
Unmatched efficiency: They remove paint significantly faster than eco-friendly or citrus-based alternatives, saving valuable time on large projects.
Cold operation: Unlike caustic (alkaline) strippers, they do not require heating the metal part to be effective. This prevents potential warping or changes to the metal's temper.
Non-reactive with metal: When used correctly and not left on for excessively long periods, they effectively remove paint without corroding or etching the underlying metal surface, such as steel, iron, or aluminum.
Understanding the Factors Affecting Methylene Dichloride Prices
The price of methylene dichloride is not fixed and can vary based on several key factors. In general, it is considered a premium, professional-grade chemical, which is reflected in its cost.
Purity and grade: Industrial-grade solvent sold in bulk will be priced differently than a consumer-ready, gel-based metal paint stripper containing thickening agents and other additives.
Quantity: The price per unit of volume decreases significantly when purchased in bulk (e.g., a 55-gallon drum) compared to a quart or gallon.
Regulatory costs: Due to health risks, the formulation, packaging, and distribution of products containing methylene chloride involve strict regulatory compliance, which can affect the final price of methylene dichloride.
Brand and formulation: Brand reputation and specialized formulations (e.g., extra-thick gels for vertical surfaces) will command a higher price.
Always prioritize suppliers who provide high-quality products with clear Safety Data Sheets (SDS) over simply choosing the cheapest option.
