Methylene chloride is a widely used chemical solvent with a diverse number of
applications. It was introduced as a replacement for more flammable solvents
over 60 years ago. Methylene chloride is commonly used in paint removers and
industrial adhesive formulations. It also is employed in the production of flexible
urethane foams, pharmaceutical products, and plastics, as a cleaning agent for
fabricated metal parts, and as an extraction solvent.

Methylene chloride is a member of a family of saturated aliphatic halogenated
compounds. It is a colorless, volatile liquid, completely miscible with a variety of
other solvents. It is produced in the United States by The Dow Chemical Company
and Vulcan Materials Company. Total U.S. demand for the chemical in 1996 was
estimated at about 285 million pounds (129,000 metric tons) of which about 20
million pounds (9000 metric tons) was imported. About 130 million pounds (59,000
metric tons) were exported.

Uses

Methylene chloride is a highly desirable chemical for many applications because
of the following characteristics:


Its aggressive solvency makes it an ideal paint remover that does not harm
wood in the removal process.

It has no flash point under normal use conditions and can be used to reduce
the flammability of other substances, decreasing the chance of in-plant fire or
explosion.

It is an effective vapor pressure depressant in aerosols.

It does not contribute significantly to atmospheric pollution through the
formation of smog, to the depletion of the stratospheric ozone layer, or to
global warming.

For 1996, the use of methylene chloride in its various applications are estimated
to be:

paint stripping
30%
adhesives
16%
aerosols & coating
11%
foam manufacture
10%
pharamceuticals
10%
chemical processing
9%
metal cleaning
8%
miscellaneous
6%

PAINT STRIPPING

Methylene chloride is the active ingredient in many formulations of paint
removers including industrial paint and commercial furniture strippers, home paint
removers, and products used for aircraft maintenance. The chemical has a unique
ability to penetrate, blister, and lift a wide variety of paint coatings. Formulations
of the chemical are used extensively in both flow-over and immersion (dip) tanks
in furniture refinishing operations. For the maintenance of military and commercial
aircraft, a methylene chloride-based product is often required to inspect the
surface for damage.
