Substitutes for ODS Solvents in Adhesives, Coatings, and Inks
Substitutes are reviewed on the basis of ozone depletion potential, global warming potential, toxicity, flammability, and exposure potential. Lists of acceptable and unacceptable substitutes are updated several times each year. A chronological list of SNAP updates is also available.
Note: SNAP Notices and Final Rules published in the Federal Register take precedence over all information on this page.
| Substitute | ODS Being Replaced | Comments |
|---|---|---|
| Petroleum Hydrocarbons | Methyl Chloroform | OSHA standards exist for many of these chemicals. Formulators should use chemicals with lowest toxicity, where possible. |
| Oxygenated solvents (Alcohols, Ketones, Ethers, and Esters) | Methyl Chloroform | OSHA standards exist for many of these chemicals. Formulators should use chemicals with lowest toxicity, where possible. |
| Chlorinated solvents (methylene chloride, trichloroethylene, perchloroethylene) | Methyl Chloroform | High inherent toxicity. Use only when necessary. OSHA and RCRA standards must be met. |
| Terpenes | Methyl Chloroform | None |
| Water-based formulations | Methyl Chloroform | None |
| High-solid formulations | Methyl Chloroform | None |
| Alternative technologies (e.g., powder, hot melt, thermoplastic plasma spray, radiation-cured, moisture-cured, chemical-cured, and reactive liquid) | Methyl Chloroform | None |
| Hydrofluoroether (HFE) 7100: C4F9OCH3 (methoxynona-fluorobutane, iso and normal) | CFC-113, Methyl Chloroform, HCFC-141b | None |
| HFE-7200 (C4F9OC2H5) | CFC-113, Methyl Chloroform, HCFC-141b | None |
| Substitute | ODS Being Replaced | Conditions or Restrictions | Comments |
|---|---|---|---|
| Monochlorotoluene / Benzotrifluorides | CFC-113, Methyl Chloroform, HCFC-141b | The workplace standard for monochlorotoluenes is based on an OSHA PEL of 50 ppm for orthochlorotoluene. | The acceptable exposure limit (AEL) for benzotrifluorides is 100 ppm. |
| Trans-1,2-dichloroethylene | CFC-113, Methyl Chloroform | The OSHA set exposure limit (PEL) is 200 ppm. | None |
| Substitute | ODS Being Replaced | Comments |
|---|---|---|
| Chlorobromomethane | CFC-113, Methyl Chloroform | Other alternatives exist with zero or much lower ODP. |
