The penetrant industry depends heavily on the chlorinated solvent 1,1,1-trichloroethane, or methyl chloroform. Methyl chloroform is used as a pre-cleaner in the manual wipe-off removal method, as a vapor degreaser in production penetrant processing, and as a suspending solvent in nonflammable nonaqueous developers. But because methyl chloroform is an ozone depleter, it is being phased out under the Clean Air Act Amendment, whereby production of this solvent essentially ceases on December 31, 1995. One of the issues facing the penetrant industry is to find effective and environmentally friendly substitutes for methyl chloroform. Several alternatives exist. Without advocating one or another, this paper examines some of the issues associated with the various methyl chloroform substitutes. The purpose is to clarify issues, not necessarily to resolve them.
