Dichloromethane: Overview

Description

Dichloromethane is principally used as a solvent in paint removers and as an aerosol propellant. It is used as a blowing and cleaning agent in the production of urethane foam and plastic fabrication and in paint stripping operations. It is used in metal cleaning, as a solvent in the production of polycarbonate resins, in film processing, and in ink formulations. Dichloromethane is used in the food industry as an extraction solvent for spices, caffeine (decaffeinated coffee), and hops. Dichloromethane's use in aerosol products includes paints and automotive spray products.
