CLEANING SOLVENTS

Substitutes for precision cleaning:

Substitute Trading mark Substituted compound Conclusion on application Specific conditions or limitations Notes
Water cleaners   CFC-113, Methyl chloroform Applicable no EPA plans to issue instructions on discharge of wastes in this industry.
Semiaquatic reagents   CFC-113, Methyl chloroform Applicable no EPA plans to issue instructions on discharge of wastes in this industry.
Pure organic solvents (terpenes, С520 saturated hydrocarbons of oil, oxygen-containing solvents, such as cetones, simple and compound ethers, spirits, etc.)   CFC-113, Methyl chloroform Applicable no If possible, OSHA standards should be complied with.
Trichloroethylene, perchloroethylene, methylene chloride   CFC-113, Methyl chloroform Applicable no If possible, OSHA and RCRA standards should be complied with.
Super-critical fluids, plasma and UV/ozone cleaning   CFC-113, Methyl chloroform Applicable no OSHA standards for ozone should be complied with.
HFC-123 MackFri®-123 CFC-113, Methyl chloroform Applicable no Has allowed exposition limit (AEL) 30 ppm.
Volatile methyl siloxanes   CFC-113, Methyl chloroform Applicable no Are suitable for the whole class of compounds.
Trans-1,2-dichloroethylene   CFC-113, Methyl chloroform Applicable no The limit of concentration is 200 ppm.
Simple ether (HFE): C4F9OCH3 (methoxynonaphthorbut, iso- and normal structure)   CFC-113, Methyl chloroform, HCFC-141b Applicable no Are suitable for the whole class of compounds.
HFC-4310mee   CFC-113, Methyl chloroform, HCFC-141b Applicable with certain limitations Average concentration of the working zone should not exceed 200 ppm, maximum - 400 ppm. no
Perfluorocarbons (C5F12, C6F12, C6F14, C7F16, C8F18, C5F11NO, C6F13NO, C7F15NO и C8F16)   CFC-113, Methyl chloroform Applicable with certain limitations Applicable in productions where all other alternatives do not suit for reasons of safety. Have long life in the atmosphere and high potential of global warming (GWP). Though their contribution into global warming depends on the amount of blowouts, the influence is inconvertible.
Users should know these application limits.
Perfluoropolyethers   CFC-113, Methyl chloroform Applicable with certain limitations Applicable in productions where all other alternatives do not suit for reasons of safety. Have the same features like perfluorocarbons.
Monochlorotoluenes and benzotrifluorides   CFC-113, Methyl chloroform Applicable with certain limitations Ultimate concentration of the working zone is 50 ppm for monochlorotoluenes and 100 ppm for benzotrifluorides. Ultimate concentration based on the standard OSHA PEL is 50 ppm for orthochlorotoluene.
HCFC-225ca/cb   CFC-113, Methyl chloroform Applicable with certain limitations Limit of concentration is 25 ppm for -ca isomer. HCFC-225ca/cb is offeres as an isomeric blend. Ultimate concentration for cb isomer is 250 ppm. Therefore, it is assumed that it is possible to accept ultimate concentration of more toxic ca isomer 25 ppm.
Dibrommethane   CFC-113, Methyl chloroform Not applicable N/A High ODP: there are other alternatives
HCFC-141 and its blends MackFri®-141b pure or in different blends CFC-113, Methyl chloroform Not applicable N/A High ODP: there are other alternatives
Chlorobrommethanecegth   CFC-113, Methyl chloroform, HCFC-141b Not applicable N/A High ODP: there are other alternatives
HFE-7200 (C5F9OCH3)   CFC-113, Methyl chloroform Applicable no
