The most utilized paint remover chemical is methylene chloride, also known as dichloromethane CAS 75-09-2, is a non-flammable, volatile chemical. It has long been the industry-standard solvent for paint stripping due to its powerful dissolving ability and fast action. Due to severe health hazards like cancer risk and toxicity, it is increasingly being replaced by alternatives like N-Methyl-2-pyrrolidone (NMP).

Why Is Dichloromethane the Most Widely Used Paint Remover?
1. Extremely Strong Solvency
Dichloromethane exhibits extremely strong solvency and can rapidly dissolve paint coatings, varnishes, lacquers, and adhesives.
2. Fast Acting Performance
DCM solvent delivers fast acting performance and works much faster than most alternatives; it penetrates coating layers quickly, causes swelling and lifting, and removes paint within minutes, which is why it is preferred in industrial paint stripping.
3. Low Boiling Point and Easy Removal
With a boiling point of around 40°C, DCM methylene chloride chemical has a low boiling point and is easy to remove.
4. Wide Industrial Applications
Dichloromethane CAS 75-09-2 has wide industrial applications and is commonly used in industrial coating removal, automotive refinishing, aircraft maintenance, and equipment cleaning.
