methylene chloride and 10-30%
perchloroethylene[SUP]
[2][/SUP] Methylene chloride is the active ingredient in many paint strippers and perchloroethylene is the most common dry cleaning fluid. They are both aggressive and toxic
chlorinated solvents. Although the manufacturer emphasizes the lack of petroleum distillates, these chlorinated solvents are more toxic than the petroleum solvent
heptane, which is commonly used as solvent for US market silicone lubricants. OSHA allows much lower permissible exposure level for these chlorinated solvents compared to heptane.
100PPM TWA
Tetrachloroethylene
25PPM TWA Methylene Chloride
For comparison permissible exposure level of heptane is much higher at 500PPM TWA [SUP]
