Methylene chloride (CAS 75-09-2) is a colourless liquid which has a sweet, penetrating, ether-like smell. It is a volatile liquid chlorinated hydrocarbon. It is non-combustible but if exposed to high temperatures it may produce toxic chloride fumes. It is widely used as a paint remover and solvent.
Although methylene chloride liquid is widely used in industrial applications, only a few products actually contain the compound as an active ingredient or component. Some of these products include:
- Paint Strippers: Many paint stripper brands use methylene chloride as the main ingredient.
- Adhesives: The compound is found in various types of adhesives, such as acrylic cement commonly used by hobbyists.
- Other Products: Trace amounts of methylene chloride may be present in automotive care products, lubricating oils, lithography materials, and certain general cleaning products. The compound is also used in cleaning medical equipment, especially components that are sensitive to heat.
