SOLVENTS, COATINGS & ADHESIVES

In the past, CFC-113 use was essential in many industrial applications: in electronic assembly production processes, precision cleaning and general metal degreasing during manufacture, as well as in dry cleaning and other industrial applications. CFC-113 began to be used in the 1970s in metal degreasing and other areas owing to concern over the toxicity of the chlorinated solvents used previously.

For many years 1,1,1-trichloroethane was the solvent of choice to replace other more toxic chlorinated solvents for general metal cleaning. Carbon tetrachloride is no longer used as a solvent in most countries because of its toxicity, but it is still used in some parts of the world.

CFC-113, 1,1,1-trichloroethane, CTC, and bromochloromethane are ozone depleting substances whose production and consumption is controlled under the Montreal Protocol. With support from the Protocol's Multilateral Fund delivered by UNEP, UNDP, UNIDO, the World Bank and bilateral agencies, developing countries are phasing out these ozone depleting chemicals in this sector.
